I recently created a couple of planets with a lot of tall mesas. I also recently played this map in Total Annihilation: That white stuff is cloud. When Gas Giants were first pitched, Uber initially thought about putting land platforms on them but after chatting with the community decided against as this seemed unrealistic. However when and if Atmospherics for normal planets do get introduced, a slider to control Atmospheric Height and Density in the way we control Water and Terrain would be awesome. We could create Venus-like rocky planets, where (at the extreme end of soupiness), the surface of the planet is inaccessible, leaving us to fight on mountaintops. I know there are lots of biomes in TA, but this one seems to be on a branch of what eventually needs doing in Planetary Annihilation with regards to Atmospherics. It'd require more control in the editor, rather than building an entirely new Crystal or City biome, for instance. So yeah! Whatcha think?
