Planets should evolve, it's fauna and flora get changes slowly. The trees get higher and stuff. And maybe some changes depending of what you do in that planet. "I made lots of machines and stuff, so the sky start to get darker." Stuffs like that. Just throwing some ideas here. xD
It would be funny if the first time you go there, your on a cliff or over lava, then the next time, the cliff got cut off and you fall or you fall in the lava
I am pretty sure they gonna have some degree of that in the game TiY worked on Terraria which had growing flora. Growing Fauna has never been done so I would like to see that myself but only for certain types of Fauna like rare Fauna that if let alone become mini bosses or Rare Adult mobs that can be caught.
