GalCiv 2 is clearly a different game, 4X in space does not have to be MoO2 spin off. Having said that, GalCiv 2 was kinda boring after a while, too abstract.

I liked the Space Empires series for the tactical battles. Somewhere on the net is a blow by blow account of a MASSIVE SE IV: Carrier Battles mod battle. Picture the biggest movie space battle with massive numbers of tiny fighters buzzing around the battleships, it must have taken the player hours just to do that one battle.
