Kerbal Space Program is an alien torturing game made by Mexican-based company, Squad. You play the game by building phallic rockets and trying to get your little green turds, or Kerbals as the game calls them, into the cold, dark emptiness of space trying to get to other planets. Playing Kerbal Space Program regularly will make you more qualified for a job at NASA than actually going to school.
An amazingspaceship building simulator that got some bad reviews because the devs updated the EULA and some people read it wrong. Developed by Squad and published by Private Division
