The mod Default Amplified Biomes will add twelve new biomes to the minecraft, in their general external style they repeat standard biomes, but they differ sharply in terms of size and overall structure. These biomes are not so realistic – they are higher, have many mountains and many trees, and the mountains sometimes look like from fantasy worlds, which is only good – this is very unusual.
