I would love to play MP - never have with any game (but I'm not a real experienced gamer by any standard.) The only thing I worry about is the time it would take.
Anyone who's played MP games, how long do they take? I assume map size/# of players/ etc all factor in, but is it typically done in a sitting? I can't find time to play any game of Civ3 in a sitting and that's with the computer making opponents moves a lot faster than I (and presumably most human players) make mine.
For the record, I'll buy any expansion pack that comes out. I really enjoy playing this game and, factoring hours of use against cost, it's cheaper than most other entertainment options, including television.
