Raynor and Wardad, thanks for the info on GalCiv. Since I, too, only have about an hour a day to play games, I should probably not get into GalCiv. I'm in a couple of SE4 PBW games at the moment, which count toward that hour, so I probably don't have enough time left over each day to really get to know GalCiv. I'll just continue the Hearts of Iron game I'm working on. Perhaps I'll be done sometime this year...
PS. Raynor, I would highly recommend PBW. It's light years more challenging than any single player game I've played.
