Alpha 7 - Things made of Stuff released
Alpha 2 - Cannibal Modders - Released
Release date: Available now at Coming to Steam when it's ready.
RimWorld is a sci-fi colony sim driven by an intelligent AI storyteller. Inspired by Dwarf Fortress, Firefly, FTL, and Dune.

Available now at Coming to Steam when it's ready.

You begin with three survivors of a shipwreck on a distant world.
  • Construct buildings to hold living and eating spaces.
  • Grow food and mine rooms into the rock.
  • Trade with passing ships.
  • Decorate your colony to make it into a pleasurable space.
  • Defend yourself from pirates and ravenous creatures (especially squirrels).
  • Weather storms and fight fires.
  • Capture refugees or prisoners and turn them to your side or sell them into slavery.
Your colonists are not professional settlers – they’re crashlanded survivors from a passenger liner destroyed in orbit. You can end up with a nobleman, an accountant, and, a housewife. You’ll acquire more colonists by capturing them in combat and turning them to your side, buying them from slave traders, or taking in refugees. So your colony will always be a motley crew.
Each person’s background is tracked and affects how they play. A nobleman will be great at social skills (recruiting prisoners, negotiating trade prices), but refuse to do physical work. A farm oaf knows how to grow food by long experience, but cannot do research. A nerdy scientist is great at research, but cannot do social tasks at all. A genetically engineered assassin can do nothing but kill – but he does that very well.

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.

You can take organs and limbs out of prisoners, replant them, remove them again and sell it for profit.

Excellent videogame.

Mutilating Prisoners is not what sold the game to me but it's complex and well thought out features. While the game is still in Alpha (Alpha 7) I bought it a few days ago and have to say it is nice and stable at this point. Random World generation, personalities on your characters, random events,..etc... just great.
