What's the speed/pacing of GalCiv2? How long does it take to get through a turn, how long does a campaign take, etc? What depth of micromanagement needs to be used for planetary admin? Can you configure the game for different sizes and densities, and are maps randomized? I think I need a game I can play for 2-3 hours at a time without getting too sucked in, and the 3am MTW sessions are starting to annoy my better half.
