Galatian would be very tempting, for the greatest part because it's got a lot of the 'stranger in a strange land' element. Greeks in Afghanistan somewhat similar. Having a faction of that type right there would be great. Mind you, we're talking 29 new factions, which will never happen, so it's just a fun thought. It would be interesting to think about CA releasing a downloadable-only version of the game (1.7?) with some hard coded limits increased. Very simple, but maybe there would be a lot of folks who would download it. I'd wager more folks would than downloaded Alexander.
