Race to Mars - A couple of simple, kid-oriented games to promote the (pretty nice) mockumentary. Moonbase Alpha - An official NASA game most people here probably already know of. Mars Simulation Project - Open source, Mars settlement administration simulator in java, apparently extremely detailed and realistic. Mars Colony Simulator - Indie 3D/first person 'RPG', looks very interesting, with even an online version, but development seem to have been dragging through years. I dig 'dreams within reach', the kind of thing people like to discuss here or on nasaspaceflight forums, and I think it's a much neglected end of the spectrum game-wise, so I focused my search on this. I'm not really into far-fetched galactic/humanoid aliens/laser guns stuff. I ended up with a pretty interesting compilation including a few rather obscure gems, and thought I should share. I'm thinking about writing one myself one day so that ispired me to do a bit of research. There was a thread a few days ago about space colonization games.
