Following its official reveal at E3 2013, check out this gameplay trailer for Take on Mars.
I think it's better than KSP and it still very early access.
This + Oculus Rift please! ^_^
Cool idea, but you might as well just play KSP
@Jerkwhad oh wait is it Kerbal Space Program?
@Jerkwhad whats KSP
@stealthyninja81 @Jerkwhad I don't see how this has anything to do with KSP.
