I think it would be neat if there were Cloud Biomes up in the sky on planets. Have floating Building and many other things in the clouds. Anyone else think this would be a great idea?
While it would be neat to have clouds, clouds are just water vapor so it would be pretty hard to walk up there, and the fall damage would be quite cruel. On the other hand adding planets that don't have a ground and are more like "Bespin" from Starwars, to me would be a bit better.
I just got back from a trip that had something like a cloud biome, with two different mine-able cloud block types in it. Stepping on them gave a jump buff that worked like a sort of glide on the way back down.
