RimWorld is a colony-builder/survival simulation game from one man dev team, Ludeon Studios. Coming up with different strategies and adapting the difficulty is one of the most fun parts about the game. It follows three survivors from a crashed space liner as they build a colony on a frontier world at the rim of known space. This game is fantastic if you like build a colony from the ground up, it's very interactive and you'll always have something to do, be it planning a new room for your base, building up defenses, creating a more reliable food source or even raiding enemy factions. RimWorld is quite complex, but perfectly accessible for anybody. If you like colony builders than this is for you. DF fans and casuals alike will find a lot here to enjoy. This will be one of the defining games of the genre.
