Actually they offer the demo free and the final version, which they will constantly update, will be for sale. But they promised to keep demo available at all time. I recalled that RPS had report some similar games, I dont recall exactly if this game has been report. But anyway, here is.

Yeah, RPS has reported on this a few times, we may have had a forum thread as well.
Any mention of KSP is good though, it's a lovely game that the world needs to know about. :)
