RimWorld is a story generator. It's 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, and each one applies a different algorithm for generating random events. So Randy Random does crazy stuff, Cassandra Classic goes for rising tension, and Phoebe Friendly just makes good things happen. So if you want a different kind of story for your colony, you can just choose a different storyteller.
