RimWorld v1.6.4543

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.

At its heart, RimWorld is a story generator. You choose one of three AI Storytellers-Randy Random for chaos, Cassandra Classic for steadily rising tension, or Phoebe Chillax for a more relaxed pace-and watch as "random" events shape your narrative. Your colonists aren’t trained adventurers but ordinary people with unique backgrounds, skills, addictions, wounds and relationships. Over time they develop friendships, romances, rivalries and heartbreak, leading to moments of triumph, tragedy and dark comedy.
