Best top-down 2D colony management game. I played it a lot before it came to Steam, but now, with the Steam Workshop it even more convenient to get a mods which makes the game much better.

• Various factors which affect colonist mood.
  
• Complex medical, surgery and damage system.
  
• Very good and atmospheric music.
  
• Pleasant graphics and smooth animations.
  
• Interesting game universe, combination of sci-fi and western. I prefer sci-fi setting much more instead of regular medieval setting like in Dwarf Fortress.
  
• Steam Workshop and lot of complex mods which improves the game significantly, and actually which makes the game great and not boring to play for a long time.

Lack of multiplayer. The game created on Unity Engine which is extremely flexible and allows to create multiplayer game easily, but for some reason author don't plan do it. With multiplayer this game will be even better, because there is no other "DF like games" with multiplayer.
