Tutorials/Building a metropolis

A metropolis is a large city with many tall buildings and people. To build one, you probably want to use creative mode. If you can create a metropolis using all the ideas listed here in survival, you are doing very well, so continue building.

Here's how to start: You will probably want flat land to start off with. There are seeds for flat land in Default mode, but get superflat if you are too lazy to enter the seed number. Superflat is not ideal for Survival mode as there are no ores, and you'll definitely want Default if you want to open mines in your video-worthy city. However, in recent snapshots, superflat cities can be made. So where do you start? That's up to you!

-Note-

1. When done, you should upload your world to a server, as many ideas are meant for multiplayer.

2. The wiki can only help you, not build it for you. Come up with your own ideas along with those on the page to create a truly epic city.

3. Please keep the Buildings list in alphabetical order!

Getting started
Before you can build your city, you'll need to find a spot to build it. In a forest or some flat land with trees if probably a good place to build. For some of the suggestions on the list, you'll need a river, or even an ocean to build, so building near water is always a good idea.

To start your city, you'll need to go to your selected building place and start building. Any sort of building will work, but you'll probably want to make it the center of your city, so keep this in mind while you build it.

There's are a few different blocks recommended for use in buildings:


 * Stone


 * Cobblestone


 * Iron Blocks


 * Wool (All Colors)


 * Wood (House/Building interiors)


 * Glass


 * Stone Slabs


 * Unused DoubleSlab


 * Bedrock or Obsidian (place between to walls of blocks for extra protection.

Becoming a city
At first, you just had a house. Following these steps, one house will become an entire city.

1. Build a new house

2. Build a place for a Villager (or player!) to stand.

3. Spawn/move a Villager/Player behind it.

5. Build more shops and houses to fill the city.

6. Don't forget to build roads!

Suggestions
Here's some ideas to get you started on your city!

City Types

 * Underwater: Build your city in a giant underwater glass dome.(Not recommended for people just starting out building cities.)


 * Venice: Make your city have canals of water (or lava) for roads. Add bridges as well. Boats will be used for transportation, but don't use boats in lava, or else they will burn up!


 * Sky: Build your city in the sky. Use snow or wool for buildings and use glass for the street. You can build the ground out of white blocks to look like clouds, or actually build it at cloud level.


 * Underground: Build your city in a cave and hang glowstone from the roof for lights.


 * Jungle Tree: Build your city in houses that wrap around the trunks of the tall trees. Use wooden bridges with wooden fences to get from building to building, or use minecarts on wooden bridges to get around the city if you want a more modern look.It can be hard making a path up the trees in survival.


 * Big Boomer: Build your City out of TNT (apart from light sources. They don't have to be made of TNT) and make the whole population of your city creepers, Ghasts and Blazes. Don't let griefers get it!


 * Nether City: Build your city in the Nether, and make it out of Nether Brick.


 * Ender City: Build your city in the End, and make it out of End Stone and Obsidian.Use ender chests for storage.Make sure to kill the Ender Dragon first, unless you hack so it wont destroy terrain.


 * Mushroom: Build your city like treetop, except use big mushrooms instead of jungle trees. Difficult to build, but worth it.Best in creative mode.


 * Castle: Build a castle in your town and surround the whole city with a big stone wall.


 * Crafty: Make your city out of different colored wool, iron blocks, diamond blocks, huge mushrooms, and other creative materials. Make the city hall of your city out of the most creative materials you can think of. If you want, you could make a Nether Portal a door for the city hall, and you can make your city hall in the Nether.Be careful in 1.4, as now mobs can travel through portals and make a bad mess!


 * Atlantis: Make a city on the ocean floor with nothing separating your city from the water! However, you and all of your inhabitants will have to be on creative mode, as if they are on survival, hardcore, or adventure mode, they will drown. Make buildings out of sponges, diamond blocks, gold blocks, and/or glass blocks, and use iron doors to get in the buildings!


 * Invisible City: Make everything in your city made of glass blocks, glass panes, and/or ice, with no doors for your buildings. However, leave the ground grass, snow, or whatever block it already is. Building an invisible city is pretty risky though, as you can't use any lights, so zombies, skeletons, creepers, etc. can spawn in your city.


 * Pumpkin Town: Make roads, buildings, and "stairs" out of pumpkins, use jack 'o' lanterns for lighting, and wear pumpkins for helmets. The only farms you can have in a pumpkin city are (obviously) pumpkin farms. Have iron golems and snow golems scattered throughout your city.


 * City of Green: Make roads out of green wool, buildings out of emerald blocks, melon, cactus, and sugar cane farms, and make your whole population creepers, zombies, and if you have mods to let you do this, green-robed villagers.


 * Magic City: Make every building in your city have at least 1 brewing stand, 1 cauldron, and 1 enchantment table, and make stores in magic cities only sell potions, potion ingredients, enchantment tables, brewing stands, cauldrons, enchanted armor, bottles o' enchanting, and ender chests. Also, place ender chests instead of regular chests.Use witches for inhabitants on singleplayer for fun, but they will kill you on survival.


 * Town of Food: Make a city out of food! Build out of melons and pumpkins, and grow sugarcane. Cocoa plants make good stairs, and use jack o lanterns for lighting (they aren't food but they are pumpkins!) Cake can be used for the floor! Easiest in creative mode.


 * Cliff: Carve your city out of a cliff, or build it hanging from an mountain overhang.


 * Hidden Volcano City: Make a volcano with a city hidden inside it. Have a hidden button which causes an entrance to appear. Have a button that you can press to have lava drip down the sides (make sure you have a way to remove and restore it!)


 * Steampunk: Make a flying city which is "supported" by giant fans, use lots of Iron Blocks and have factories with Cobwebs coming out chimneys for smoke.


 * Twin Cities: Have two cities next to each other. They could be deadly enemies, or a city where the rich live and one where the poor live.


 * Futuristic Skyscraper All-In-One: Best for any biome, just need place for pillars. Preferred for creative. A massive, costing... and perhaps ugly structure. If you want your inhabitants to feel like being sheltered or compressed together, this is the best solution. It's designed as a heavy skyscraper with many districts and zone scattered trough it. You can build it of any form - Just remember to be futuristic and realistic. It can be a real maze with multiple layers and floating parts.. or a simple big prism with many corridors. Try to make it feel as if a nuclear disaster fell on the world and the ground-level towns are infected by zombies and that the toxic air obliterated the open-air districts. Your "roads" may be accessible by walking, and may be built with glass cover. They pass trough plazas like some kind of highroads. They give rapid access to certain parts of the skyscraper because it is divided by many areas. You can have some layers, some "zones" restrictions and much more. Remember to have solid, hard pillars made with obsidian or iron blocks to sustain your maze of hallways protuberances. The pieces may be linked together by growing onto sides of roads. Here are examples of layers or "zones" :
 * Level 0 to 4 = Death zone. Sas to the outside. Everything, except authorized military patrols with radiation suits,(Armor of your choice.) will be flagged an infected entity and will be killed.
 * Levels 5 to 22 = Military zones. Access restricted for armed soldiers or highly authorized federal agents, scientists, test subjects or politicians.
 * Levels 23 to 64 = Heavy Industrial zones. Big factories with high polluting. Laboratories. Sewers. Redstone power lines.
 * Levels 65 to 80 = Poor zones. Low value housing. Low value pawn shops. High crime areas. Very populated zone. Army outposts.
 * Levels 81 to 100 = Mid zones. Lots of basic apartments. Individual homes (3 peoples or more). etc. ...
 * Think about a futuristic city built in one huge building with floating parts, all these linked together. Try combining with Ruins or Steam punk city type for best effect. Note* this doesn't HAVE to have 100 levels, this is just an example.


 * Space: Build your city at layer 200 and make the roads obsidian and the buildings iron blocks and stone slabs. Add a lot of redstone circuits to your city. You can also add wormholes (Nether Portals) and lasers (flowing lava) to your city. To make it more space-like, you can surround your city in black wool. Go through at least one of your "wormholes" into the Nether, and then expand you city into the Nether! It will look like space at night, as because of a glitch the sun will appear opposite the moon! Fortunately, Mojang doesn't want to remove it.


 * Vertical: Build a huge tower out of any material you want. Then, use ladders to travel across the city and make the buildings stick out of the tower. Make this tower very tall and wide.


 * Beanstalk: This city is a combination of a sky city and a vertical city. First, build a very tall tower completely out of leaves or green wool (or both). Use vines to get up, and add buildings sticking out of the tower. Once you get above layer 50 (the cloud layer), change your buildings materials from leaves/green wool to normal wool or snow. You can make the buildings out of either wool/snow or wooden planks and stone (normal building materials). You can even build an ENORMOUS capital and hack a giant to run the city. If you do hack a giant for your mayor, also get a civilian of your city to be an offering; that is, they are fed to the giant.


 * Maze: Make your city a maze: that is, make it hard to go through without getting lost. Make your city hall/capital in the middle of your maze city.


 * Ruins: Make the ruins of a once great city and add small shelters scattered around the city Keep only the shelters lit and keep the rest of the city dark so that hostile mobs will spawn. Use TNT to put holes in streets and buildings to make it seem like they are falling apart. place chests around town and put weapons and valuable items inside pretend that the players are the only survivors in the city and you must scavenge food to keep your hunger bar up fight off any monsters that assault your base and other things keep the difficulty set to hard to keep it realistic.


 * Monster Village: Make a village out of bedrock, obsidian, monster egg stone and other creepy stuff, with LOTS of monsters. If you have mods, make spawners hidden in "tombs" and have the difficulty on hard. Definitely a creative-mode city to build. Be creative and make stuff like huge haunted houses, mob farms and mob arenas. Hilarious but offensive in hardcore.


 * Igloo Village: Make a village out of snow. Ice can also be used, but it will melt in light. Make all of the buildings dome-shaped, and place snow golems around the village for protection. This is a very easy village to build and gather resources for, but it is vulnerable to mobs.


 * Desert Village: Find a desert your village in it. Make it out of sandstone and use irrigation to make farms. Also add a Mosque and some palm trees made out of jungle wood and leaves.


 * Giant Village: Make an NPC Village or find one and expand it into a sprawling metropolis inhabited by countless Villagers. Bring plenty of Villager Spawn Eggs.


 * Zombie Apocalypse:' Build a "Ruins" style city and use Spawn Eggs to fill it with Zombies, Villagers and Zombie Villagers, and you must command a squad of Villagers or other players in a game of survival! Play on Hard difficulty.


 * Robot City: Make a futuristic city out of Iron blocks and fill it with Iron Golems and redstone mechanisms to make a mechanized robo-city.


 * Floating Island: Find or build a floating island, preferably over an Extreme Hills biome, and make a magnificent sky city!


 * Void: Create a superflat world with only one layer of block. Build a tall structure and then blow up the ground, exposing the void. Then use the tall structure to build blocks off of and make an awesome Void city!

Transportation
You need a method of transportation for your city to get around. Here are some ideas:
 * Walking: The most common way is by walking, so build nice wide roads out of stone and pavements out of stone slabs. Have signs pointing to important buildings or where you want people to go (signs to the casino is a good idea to make money!)
 * Minecart: You can make a subway or overground railway to get people around. See Tutorials/Train Station for more information. Set up ticket booths and charge people, allowing expansion.
 * Boats: If your metropolis spread across islands, then build a boat network. Have harbors at every island and make wool pillars in the water (buoys) with signs directing people to other harbors. You can also have canals, but these might get in the way of your pavements.
 * Desired Setup: Build pavements linking your buildings up, then build a minecart system. It can be simple. Finally, use the harbor idea for island metropolises only.
 * Pigs: After the 12w36a snapshot or above you can control pigs using carrots on a stick so you could have like a car system. add "gas" stations selling carrots on sticks.
 * Teleports: With the addition of Command Blocks, you can now create redstone circuits which activate console commands. Build "stations" with Command Blocks in them, which have the command " /tp @p  " to teleport the nearest player to the Command Block to the specified co-ordinates.

Buildings

 * Airport Build an airport and add a runway to "fly" planes off of.


 * Arcade Build a building and make the walls out of colorful blocks and fill it with fake games made of iron, paintings, and signs.


 * Arena A player arena and a mob arena in one! You can make it look nice-ish on the outside, but the inside should be bedrock. Have torches and glowstone, and mob-dispensers for the mob arena and have plenty of temporary weapons for rent in the "arena store" or whatever you want to call it. Be creative.


 * Auditorium A place for people to gather and watch something, like a concert, speech, etc. It should be able to seat a lot of people. Can be placed in the Town Hall.


 * Apartments/Hotel Build a tall building out of bricks and fill it up with rooms with a single bed and small chest in each. People rent the rooms for whatever you are using as currency and can store their stuff there and sleep.


 * Nether Colony Build a small village in the nether to expand your city beyond the realm of the overworld.'''


 * Bank People go here to store their money. Have a trusted person work there and have vaults deep underground to store their gold and diamonds. Only let the trusted person and the owner of the vault into it. You can use piston doors on the vaults that need a special "key" (Lever)


 * Bookstore/Library Fill a shop with bookshelves. Have a librarian villager work there and have authors write in books and quills to buy/borrow. If the building is a library, fine players for not returning a book on time, or "damaging" it (losing it or destroying it). Have a minecart with chest connected to a minecart train filled with books. Also to make citizens happy, let them write their own books with book and quills.


 * Cake Factory Build a factory that makes cakes. You could connect it to the bakery. Have a chicken, cow, sugar, and wheat farm under it, with automated egg, sugarcane, and wheat harvesting.


 * Casino Have a big fancy building with minecart slot machines (minecart in, random items out) or pig slot machines (using random pig movements.) Make it out of gold and diamonds.


 * Cemetery Build a cemetery building. You could use iron bars to make a fence, and an iron door to enter. Then add graves inside. Make tombstones out of stone bricks and dig holes under them. If you have access to a world editing tool, you can place zombie or skeleton spawners under them.


 * Church Have a big building to worship the gods known as Mojang.


 * Dance Lounge Have a multi-colored wool for a dance floor, and use redstone lamps (whatever you want to do with it). You can use obsidian for walls. You'll have a blast!


 * Department Store/Mall Make a huge building with many floors that sell different items. Have a floor for blocks, Armour, food, and mob drops, ETC. for different prices. In a mall, add each store in a separate room.


 * Some stores to add would be:


 * Potions shop – A place where you can buy all kinds of potions.


 * Enchantments shop - A place where you pay someone to enchant your tools/weapons/armor.


 * Food market – A place where you can buy any kind of food.


 * Local shop – Sells everything but junk food (cake or cookies, maybe pie). May also sell tools and armor but probably nothing past iron. (may also have a higher price than specialized shops).


 * Clothes shop – This shop only sells armor in it. Dye leather armor and sell it as "designer" armor!


 * Garden shop – this shop will sell flowers, flowerpots, saplings, bone meal, water buckets, dirt/grass blocks, sand, cactus, nether wart, seeds (all), melon, pumpkin, hoes, red and brown mushrooms, lily pad, vines, sugarcane and any other farming resources that exist.


 * Exotic shop – This shop sells items that are a little more difficult to find such like glowstone, lapis lazuli, blaze rods, ender pearls, gold nuggets, apples, golden apples, music discs and eyes of ender.


 * Forge – Charge people to craft a tool or smelt a block.


 * Building shop – This shop sells common and exotic building materials such as stone, cobblestone, brick blocks, glass, glass panes, netherbrick blocks, obsidian, wood, wood planks and bookshelves.


 * Junk Food shop - A junk food shop will sell cake, cookies, pie, and burgers (steak + 2 bread). Make sure no healthy food goes in!


 * Redstone outlet - A shop which sells all things redstony. Have some examples of redstone going underground like a piston lift, a piston clock or an automatic farm/cobblestone generator.


 * Pharmacy - A shop with potions (but only good ones) and all foods except cake.


 * Scrap shop - Where players trade in beaten armor, damaged tools and blocks they have no use for, then the owner sells them to people who can't afford full grade armor.


 * Music shop- Sell rare music discs and jukeboxes for a high price.


 * Pet Shop- Here, you can sell wolves and ocelots. They are sold untamed, and then the buyer can tame them if they want to. You can also fill chests with dog food (rotten flesh and bones) and cat food (raw fish). If you want, you can even sell spawn eggs (Watch out with the hostiles) and golems (iron and snow). Remember to keep the pets in cages, and optionally have a home delivery service. Be careful, as the wild ocelots will despawn.


 * Bakery Have a building dedicated to selling bread, cookies, cake, and pumpkin pie! You can build a giant model of the Minecraft Cake out of colored wool and have the inside be hollow. Fill it up with "shelves" (wooden planks) with signs on them listing what is on them. At the counter, costumers can order cakes, cookies, and bread. Ship cake in from the cake factory.


 * Dog Pound Fill a building with wild wolves in cages and sell them to people. Give them bones until the dog is tamed. Smacking wolves is forbidden and anybody who does will be sent to jail.


 * Embassy Make other peoples' voices heard! Build offices that represents another server, a nearby city, or even mobs like testificates, creepers (build walls out of obsidian or they will blow up the rest of your city), or endermen! Also remember to build them next to your city hall.


 * Enderman Art Show Put endermen in a room of blocks they can pickup. After a set amount of days, see how they changed it! Players can bet on certain blocks being moved. Make sure that the endermen are kept in a glass cage, though, or players might look at them and make the police come in!


 * Farm Have wheat, melons, pumpkins, and sugar cane growing. Raise and breed cows, chickens, pigs, and sheep. Sell the food and wool you get from the farm for iron and gold. Sell animals for gold.


 * Fire Station Griefing protection is first and last, but your wood constructions need a plan B. Fill a house with water buckets, armor enchanted to fire protection, and minecarts ready to move out in maximum speed. Block 51 must die! As an extra measure, you could have a button in all of the houses to call the fire station, connected with redstone. In the fire station you could have a wall of redstone torches, corresponding to the towns buildings, so when someone presses a fire button, the corresponding torch would light up. Just an idea.


 * Garden Make a big grassy area in the center of the town full of trees, flowers, and tall grass. Use street lights along a road to keep hostiles from spawning. If you feel creative, constructed a lookout tower with a spiraling staircase up to the top, which has a view of the whole city. You could also add attractions such as caves filled with ores and charge people for a guided tour. Be creative with it, but don't go too far.


 * Harbor Can only be built if your town is near the ocean. It will be useful if your town is spread across several islands. Craft boats and build giant ships. Charge money to rent a canoe or rowboat and charge even more if it breaks.

Build a big building and fill it up with hardware materials such as wooden planks (in all colors), cobblestone, stone etc. make the shelves high and use ladders to get to them easily. Have many checkouts with people manning them.
 * Hardware store


 * Highway System Make a highway system in your city! Make exits and entrances in the highway. If your city is a big one, you can make several highway roads around your city and you can have them connected to each other. These can also be used to connect two or more cities.
 * Hospital A place to care for injured players. Free beds and healing potions for everybody!Some players had a bad night, so they need some refreshing. Make a BIG house with a red cross on it, and fill it with beds, healing potions, surgery rooms, and that kind of thing. Hire "doctors" and get them to wear nurse and surgeon skins. You can even sleep in one of the beds there, and you will wake up there after a bad episode!


 * Ice Rink Only possible in creative mode, unless you are willing to spend lots of levels trying to get silk touch on a pickaxe. Place ice on the ground inside of a building and skate around on it. Have contests to see who can skate the fastest or spin the longest. Keep fire, glowstone, and light sources far away from the rink, or it will melt!


 * Jail When people break the rules, send them to jail! Build lots of cells inside of a big building and lock people inside. Make sure an admin changes them to Adventure Mode! Bedrock and lava is another great idea!


 * Stadium Have a big stadium where players can compete in sports such as spleef and paintball. Add lots of seating for people can sit and watch.


 * Temple Though it may seem similar to a church, it isn't the same thing. You can make a humungous temple, or a little tiny shrine the size of a sandstone well. You can have an area for training in magic (if appropriate), a way to sacrifice, table, lava, bottomless pit, etc. And make sure the temple makes sense; for instance, put a god of shadows underground,and a god of time and space with things such as end stone and other mysterious things. Gather priests and give them cows and pigs to sacrifice.


 * Theme Park Have a fun place with minecart roller coasters, a haunted house, and a maze.


 * TV Studio Pointless but it gives people something to do such as filming soap operas or winning gold and diamond on a game show. Hire directors, producers, actors and actresses, build TV show sets, have pretend ratings etc. This could provide a lot of fun for players on a server.


 * Upgrade Shop A place where people can upgrade their tools or armor for a price that depends on what level of armor your upgrading from.


 * Zoo Try to get one of each mob in a chamber where players can look at them. Be careful with the hostiles, and make mini-biomes resembling a mob's home.

More Ideas
Anything that doesn't really fit in anywhere else goes here!


 * Pest Patrol When annoying mobs invade, call the pest patrol! Remember to include tamed wolves,tamed ocelots, iron and snow golems. Don't forget weapons, TNT, and armor!


 * Holidays Have special days to celebrate. They can be real or fictional, just have fun!


 * Games Build an area where players can play games like:


 * Target Time!' A game where a bow is used to shoot a wool target.
 * Pork Pusher!: A game that includes a big, black, hollow box with a glass pane screen representing a TV. The inside is decorated colorfully. Outside, by the screen, are 3 levers representing joysticks on video game controllers. The levers operate 3 pistons, inside the TV. The player attempts to push a pig around as many times as they can. If the player makes 20 successful pushes, they push a button that drops a cooked pork chop on them. If the player fails, they push a button that opens a pit below them, leading to their death.
 * Wolf-run!: A game where there are wolves. Hit and run and see who can survive the longest. 2+ players.
 * Graveyard: A Graveyard with Spawner's under graves.Hide chests with armor and weapons. 4+ Players.
 * Pig Hunt: Build an arena with pig spawners in the middle and a colored pit at the corners. Players get One wheat and abduct pigs. Can be done with zombies for DEATH!
 * Spleef: Mentioned above.
 * Drop Party: Players are put in a room while the admin drops items like pistons and sugar and lava and nether portal blocks (Random stuff) these can be taken home later.
 * Take 'Em All On!: A game that a player goes into a dungeon filled with traps, bunkers to sleep in, hostile mobs and an Nether Portal. Go into the Nether and wander around to find the end of the dungeon, a bunker containing a prize and a portal back to the overworld. 1+ Players. Inspired by Take Em All on in Legend Of Zelda: Spirit Tracks. An example of a dungeon is:
 * Room 1: 5 zombies


 * Room 2: 5 skeletons


 * Room 3: 5 hostile wolves


 * Room 4: 1 creeper


 * Room 5: Mini-boss: Enderman


 * Room 6: Resources and Portal


 * Nether Room 1: 5 Zombie Pigmen


 * Nether Room 2: 3 medium Magma Cubes


 * Nether Room 3: 1 large Magma Cube


 * Nether Room 4: 3 Blazes


 * Nether Room 5: Ghast Boss


 * Nether Room 6: Return portal


 * Prize Room: Reward for finishing is inside of a chest or dispenser.

During a game, no-one else can play. At the end of each game, the owner of the game switches to creative mode and rebuilds the dungeon. As an alternative, world protection tools can be used to prevent damage. Learn more at the Zelda wiki.
 * Paintball: Players are put in an arena. They are given bows and arrows then fight but remember winner takes all. There are multiple variations like Cap the Block, Domination, President and Regular.
 * President: A member of both teams is given a leather cap (the "president"), then first team to kill the others "president" wins.
 * Cap the Block: A game where a dirt block is placed in the arena then players have to retrieve the block and place it in their base.
 * Domination: Same as Cap the Block but there are multiple blocks in the arena. The first team to get the most wins.
 * Grand Theft Egg!: Put an Enderdragon egg in a big dungeon with hostile mobs and traps. If a person or team manages to get the egg and back out they win.
 * Pressure-plate Fishing: Put a 3*3 chamber with a hollow tube in the middle. Create multiple of these, and remove the middle walls. Then, put a hole in the front, middle, top section of chamber and cover the tops of the chambers. Wire the pressure plate to redstone. The player uses a fishing rod to try to hit the pressure plate.
 * Puzzle House A series of rooms that require the user to use logic in order to move on to the next room such as a hidden door behind a painting or a code written on signs needed to find the correct sequence of levers to pull. Leave it for someone to figure out. You could also charge people admission and add a time limit. Whoever gets out before the clock stops gets a prize.
 * Maze For fun you could build a giant maze, or a labyrinth filled with zombies and skeletons. Make it as dark as possible with traps and pits. Or a lovely pink one with plenty light. Maybe a hedge maze is of your taste. Possibly a neat, complex forest maze will satisfy your hunger for something to do. Or you can be cruel to your test subjects and use pistons and timed randomizers to make an ever-changing puzzle.
 * Monster Hunter: Make three rooms out of cobblestone (expect the floor) that are connected with iron doors. Then make large windows for each of the rooms. Then add different mobs in each of the rooms. For the first room, add zombies, skeletons, creepers, hostile wolves, spiders, pigs, sheep, slimes, and 1 zombie pigman (the boss of the level). This will be the overworld level, and the floor will be grass, with puddles of water as well. For the next room, add zombie pigmen, blazes, magma cubes, and 1 ghast (the boss of the level). This will be the Nether level, and the floor will be netherrack, with puddles of lava as well. For the final room, add silverfish and 1 Enderman (the boss of this level), as well as a small obsidian pillar with an Ender dragon egg on top. This will be the End level, and the floor will be end stone. To play, you get a bow and try to kill the monsters. However, if you shoot a pig, sheep, or slime in the overworld level, you will lose points. Once you are done playing, you will be able to go in the rooms and collect the mob drops.
 * Trick or Treat: Make a large room with a "town" in it. Inside the buildings there will either be another player which will give you prizes, a villager which you can trade with (via a chest full of emeralds inside the building), or a dangerous mob. The dangerous mobs will either be zombies, skeletons, cave spiders, hostile wolves, silverfish, or blazes. The buildings are made of nether brick, with gravel roads and cobblestone stairs.
 * Super Tamer:

Have lots of players get a stack of bones and have them tame as many dogs as they can. They may not want the dogs, so they may kill ones they don't want. Can be done with ocelots for HARDCORE!


 *  War Minecraft has never been peaceful (unless you play peaceful) and never will. Build forts, bunkers and wage war against castles full of traps, monsters (creepers are not recommended), other player, and challenges. Build TNT cannons and build an army. Award loyal soldiers with positions like the general.


 *  Weapons License In a peaceful city, players shouldn't be running around murdering people! You can set up a system where anybody holding a weapon without a license is thrown in jail. Set a price and expiration date and only let trusted citizens own them.


 *  Training Make a massive training area that teaches the player every single trick in the book of Minecraft. From splash potion jumping, to sniping with the bow and arrow. If you think that the player is experienced (both in terms of skill and actual XP points) enough, then it is possible you can recruit them for a guard.


 * Nether Access Build a portal and let people get to the Nether. Even better, if it spawns you right next to a Nether fortress, then you can make a tour and block off dead ends. Or just make a netherrack mine. Build a nice nether-style building around the portal so people can easily see where it is. Cannot be made in End or Nether cities, consider "Overworld Access" there.


 * Ghastbusters Gather up some players to go to the nether and fight Ghasts and Blazes. Give them fire resistance potions and enchanted bows and watch the Ghast Tears pile up!


 * Defense Don't let the monsters take over the city! Make sure you have walls around your metropolis. Put cacti on top of the wall to keep spiders out. You can also add archer towers if you want. Just make a 3×3 square on the wall with ladders to get up to them. Add moats with lava for death of your enemies. Just be creative!


 * RacesThis would be an arena that is long and has seating on the sides(they could be going up like a slope) dig a 1+ block deep canal in the middle and have it at least 5-6 blocks wide. Fill it with water source blocks. Put some turns and obstacles in it and you can have boat races!


 * National Park Close off an area of your metropolis and leave it how it is, with forests, caves, NPC Villages, plains, deserts, taigas, tundras, oceans, rivers, temples, abandoned mineshafts, strongholds, dungeons, jungles, etc. Make a Leave No Trace rule here (e.g. if someone builds something, they have to take it down once they are done using it, they have to replace blocks they destroy with the same block, they have to use spawn eggs to replace anything they kill, etc.), and if they do not follow it, they will go to Minecraft prison (which is mentioned above). While constructing your national park, make cabins for guests to stay in, with a few bedrooms, a bathroom, a living room, a kitchen, a balcony, etc., and use gravel roads to connect them. Also make a no mining rule. If there is a stronghold located within your national park, dig straight down until you get to the stronghold and then add ladders so people can get there. It is also advised to activate the End Portal. National parks can also be made in The Nether, with the same rules as Overworld national parks.


 * Pet Show For both cats and dogs. Have events like for the cats scaring creepers into a pit, and dog killing as many mobs as they can. WARNING: The dogs might die, so be careful! Have pets enter 1 at a time. Heal it between rounds.


 * Redstone Build weird mechanisms with redstone in your buildings or make areas full of them that makes your city look more advanced. Such as wiring all the buildings so they have electric lighting. Or make a clock tower, or track your resident's movements, or have streetlamps that turn on at night.


 * Building Contests Maybe who can build the best flying machine? Or maybe the best new building for your city? Have judge who will give the winner a prize. The one who wins will also get to keep the building,the losers will have to remove their buildings.


 * Historical District Make this part of your city more historical such as medieval buildings, Victorian buildings, any old fashioned era you can think of! Make sure there's a good few museums around here. You can even go back to the time of the Neanderthals!


 * TP Hub: Use Command Blocks with the /tp [coordinates] command to make a TP Hub for fast travel. A cheap alternative to making a massive Minecart railway system.


 * Interior Design Nobody wants to live in a house without furniture! In every house you build (you should end up building a lot of them) add special furniture. Use pistons or fences with pressure plates for tables, stairs and signs for chairs, and bookshelves to decorate your houses. Try making a computer with an iron block and a painting, plus redstone and a lever to be a mouse.
