• If you like/are interested in the tycoon type of RTS management games, I really enjoyed Jurassic World Evolution. Instead of building an amusement park, you build a zoo of dinosaurs, often rescuing them from the wilds (after they escaped from the movies).

    Otherwise RimWorld, which you said you have, and Dwarf Fortress are the classics but can be hard to get into. I hate recommending going to YouTube, but I know there are some “let’s plays” that can really help you get over the hump that comes after the tutorial.
