I also like MOO the best because of the lack of busywork. In a way, it feels a lot like a Euro board game, with sliders instead of meeples working the planets.

Well, like a Euro except for the glassing your opponents' planets part; genocide is kind of rare in cardboard. But it is possible to play and win without doing that, in most games anyway. And then you're playing a game where if you collect enough "points" from your economic engine -- population from terraforming -- you win the game. Now can you offer further explanation of this "interplanetary rail" thing? Is it Galaxy Express 999 style?
