Tutorials/Building a metropolis

Due to a desire of redoing this page, the current page Tutorials/A metropolis is being editted once again.

Have you finished building your house, explored all the mineshafts, defeated the Ender Dragon and don't know what to do next? Well, your next objective could be building a metropolis. A metropolis is a city that never stops growing, with lots of skyscrapers, buildings, and flags. Flatland is ideal for this, but do this in Creative Mode as there are no ores for this in Survival Mode. And yes, there are seed numbers for flat land for Default mode.

Getting Started
After uploading your world, you'll need to start deciding on what type of metropolis you want. It's ideal to do this on a server, as players will spawn to your city. Be warned, though, use Singleplayer if you don't want them to destroy anything.

Types of Metropolises
Here are a couple of ideas. Note:Do not submit ideas that already have been repeated before, and, due to a tag for almost deleting this page for violation, please do not submit wars, nightclubs, etc, as few people want this type of thing in their metropolis.

Ancient City Use diamond blocks, gold blocks, iron blocks, and lapiz lazuli blocks for a magical city that contains villagers (you could use them as elves because my brother did.), Iron Golems, and a statue with a burning Netherrack torch.
