Alpha 2 - Cannibal Modders - Released
40K on Kickstarter, Gameplay Video
Release date: Available now at, on Steam in 2014
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 in 2014.

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 know what, I think this game looks absolutely amazing and I can't wait to play it. I can only see one issue: the price. I am a cheap person, and I'm not willing to pay 30$ for the game. I'd pay 15 at the most, 20 if I think I really, REALLY want it at the time. However, the came looks so well designed, and so well put together already that I would be willing to play it or buy it now if the price was a bit lower. +1, no, +100,000,000

I can' wait for this!! Looks like what I've been searching in a game for a while. If modding would be available I'm sure I'll be able to find (or hopefully create eventually) something more! But I don't have paypal so I gotta wait for steam!

So assume that I buy this game from the Rimworld website. When the game is released on steam will I be able to have it on steam as well?

Ce jeux à l'air extrêmement prometteur !
C'est un jeux basé sur le survival, avec des vagues d'ennemis toujours plus nombreux, il faut donc bien penser sa base et faire très attention aux besoins et à la survie de nos survivants en ayant des bon alliés.
Chaque survivant a des affinités à une certaine tâches qui à donc un bonus d'expérience jusqu'au lvl 20(max). Un mineur ira plus vite à miner alors qu'un autre basé sur le social pourra mieux persuadé les prisonniers de nous rejoindre.
Grâce aux mods, il est possible d'avori pleins d'armes differentes, des tourelles efficaces, des défenses solide, de nouvelles énergie (centrale nucléaire etc ...), de l'esthétique pour notre base, du commerce plus approfondie, changer les ennemis en créatures de starship troopers et j'en passe et des meilleurs !
On peut mettre 10,20 voir 30 mods en même temps, le jeux tiens le coup.
Ce jeux est à surveiller de très près, qu'attendez vous pour nous le mettre sur steam !!!

The devs seem to be waiting until there's more content in the game to have it worth releasing on steam. Patience, or buy it from their website. It's all the same.
