So, I've seen the list of biomes, and I had an idea, one biome per planet. And here's a list of biomes. -Jungle -Artic -Mountainous -lava World -Plains -Swamp. -Heavy Forest -Islands -Cave -Tropical Rainforest -Ape Planet.
I think I have read somewhere that each planet will have an overarching biome divided into different kinds of sub-biomes. So even if each planet is randomly generated it will be generated within the boundaries of its overarching biome.
Yeah, so one planet would be a lava world biome, for example. But within that planet are sub-biomes of active volcano, defunct volcano, obsidian plain, lava tunnels, etc.
