I would like to rally the forces of RimWorld here. I love the game, even though it's early access, but hell, it's pure survival from the beginning to your miserable end. There's a lot to do, and the game frequently get's you into hilarious situations, and everything you do, you may regret the moment after.
The base game is getting updated constantly, and there is already a huge load of mods!
