I think it’d be interesting to see Artificial Intelligence in the game that’s self learning. In the sense that an AI is put off in a closed environment and they’re built up to learn how to craft, farm, store, build, etc. once they reach a certain point that build of them is saved and released in the base game and so you can run across AI building there own home’s, dying in the wild, possibly banding together to create a functional town ecosystem, etc. They’ll progress as they learn within the game and should the player choose to restart all of there progression is wiped. Each difficulty setting is a different level of progression and maybe what the AI experiences in there own little life results in how they’ll address the human player whenever they come across them.
