RimWorld is a sci-fi colony simulator that excels at generating emergent stories through an intelligent AI storyteller. You begin with three shipwreck survivors stranded on a distant planet and must guide them through every trial-from starvation and disease to pirate raids and planetary disasters. Inspired by Dwarf Fortress, Firefly, and Dune, RimWorld blends deep simulation, tactical combat, base-building and rich character drama into one addictive package.
