I had played this game for over 250 hours prior to getting Space Race. While I love some of the new features, some of the situations have ruined games for me. One example, I have over a 140 colony slots and a new colony ship arriving when I am presented with the situation that I could either leave my colonists alone and lose 10 morale, or give them more space and gain 10 sanity, or something like that. I chose the latter, and suddently had over 300 homeless colonists, and nothing I could do about it. In my opinion that game was ruined, and I don't want to play it again until I can get rid of this expansion. Sure, the new features are nice, but stuff like that is a game breaker. I play for fun, and that is not, in my opinion, fun. So, how do I get rid of Space Race and go back to the older version of Surviving Mars?
