I'd like to know where this rumor that Moon takes place in the 60's came from as well. It's never explicitly stated anywhere in the game. The description for the map has a quote from JFK which is dated from the 60's, but it doesn't say anything along the lines of "I believe that this nation should commit itself to achieving the goal, before this decade is out, of bulding a giant space station on the moon."
