RimWorld

Imagine the ASCII insanity (and depth) of Dwarf Fortress, but give it a simple but attractive GUI and set it in space and you have some of an idea what to expect from RimWorld. Three survivors from a crash on a planet at the rim of the known universe and must build a colony and survive. Opposing them are the elements, the biome in which they are situated, the personalities of the survivors and a game AI that will pose threats based on what the players are doing.
