Amplified

Amplified, sometimes stylised as AMPLIFIED, is a world type that was added in Minecraft 1.7.2, it consists of many large hills and mountains which dwarf even the extreme hills seen in all other world types. It is unclear if the skylands effect that this world type brings on is intentional, or simply a limitation of the Minecraft world generation. This world is recommended only for a "beefy computer" because due to it having the extreme hills, it will need a lot of power to even generate the world. This world can be particularly hard to survive in since few caves generate in the hills and it's quite easy to fall to your death off a cliff. Certain biomes (i.e. swamplands and oceans) may see little to no change, however.

Trivia

 * This world generation can generate several floating islands, similar to Skylands
 * It is recommended that you have a powerful computer to play amplified as it uses a good chunk of RAM.
 * AMPLIFIED was actually created by accident - Jeb was fiddling around with the terrain and accidentally made the generation take up the entire world height. Notch saw what Jeb had done and convinced him to keep it as a world type.
 * Despite NPC Villages needing flat ground to generate, they still spawn in this world type regardless of how flat the ground is, causing the villages to spawn in abstract ways.
 * Worlds in Minecraft Pocket Edition might be slightly Amplified, because rarely floating small islands are formed.
