RimWorld is a story generator. Its designed to co-author tragic, twisted, and triumphant stories about imprisoned pirates, desperate colonists, starvation, and survival. It works by controlling the “random” events that the world throws at you. Every thunderstorm, pirate raid, and traveling salesman is a card dealt into your story by the AI Storyteller. There are several storytellers to choose from. Randy Random does crazy stuff, Cassandra Classic goes for rising tension, and Phoebe Chillax likes to relax.
