I wish there were a wider variety of fauna. I imagine if they made them as a moddable component you'd see the mod community add a bunch.
It's actually one of the aspects of Don't Starve that I love. Practically everything in the game is some sprites, sounds, and Lua. That makes it fairly easy to extend the game.
Satisfactory is early access, though I have no clue how close to finished they are. (Though, from what I have played -- just got up into Tier 4 -- it feels really complete)
