I don't actually care about canon-based systems, and it seems to be the way you're leaning so maybe this is a useless comment
but since you asked, I am excited to explore some just weird alien places that we get to make up, things like a Pirate World But There's Also Robots, or Fast And the Furious: Dinosaurs, or a like microverse Everything Else is Really Big (we are tiny and live like mice and drink out of thimbles).
