Whoops I posted this response in that other item, meant to put it here...
Hopefully the upcoming patch will, as the support staffer said, fix the problems some people are having with memory leaks and the like. However I'm concerned that thamer's note above said absolutely nothing about the patch addressing the GameSpy multiplayer problems, which are pervasive and are really holding back the game. I personally know two would-be Civ players who are simply unwilling to try the thing again as long as the multiplayer connectivity is so infuriatingly broken; the GameSpy lobby is rife with similar reports.
The two killer GameSpy issues are the "bad peer" problem, and the game hanging when a player retires as opposed to just exiting to menu. Please tell us that the upcoming patch will deal with those?
