The problem I have with Minecraft’s biomes is the word “biome” (which means “climate zone”, btw). It’s too close to “Boom”, which means I end up singing “Biome, biome, biome, biome, I want you in my room!” whenever I read it. Mojang’s problems with the biomes, however, are a bit less childish: the rules used to create variety in Minecraft’s world generation means there’s often unrealistic placement of zones. Desert and snow bump up against each other, there are uncrossable oceans separating continents, and there’s not enough variety between chunks. Version 1.7 seeks to change those rules.
