The downside of adding biomes is, particularly for single player, that it becomes more difficult to find a biome you are looking for. Instead of just the 7 vanilla biomes to traverse, it becomes much more possible to need to cross two jungles, three plains, two mountains, four forests, and three more swamps before you finally find a desert with the cactus you need. So I do prefer keeping the biome list as slim as possible while still getting a good diversity. Here is a list of Biomes 'O Plenty biomes I came up with as a reduced list:Bamboo ForestCherry Blossom GroveCragGardenHeathlandHighlandHot SpringsJade CliffsLush DesertMystic GroveOrchardOrigin ValleySeasonal ForestShieldWetlandI am also a little unsure of the nether biomes, particularly Corrupted Sands and Phantasmagoric Inferno. Of course part of it is lazyness, they tend to pave over the netherrack, making it more work to find ores in the nether.What do you guys think?
