hey, I am still somewhat new to the Mac (I got my iMac in January) and have not played games on it yet...I'm a fan of strategy games, and was wondering if I should buy the Mac or PC versions of games (specifically Civilization IV or Age of Empires)? I have Windows XP running under Boot Camp, and would prefer to use Mac OS X as much as possible, but not if the games will run much better under Windows...I have a 20" iMac 2.33 Core 2 Duo with 2 GB of ram. If anyone has played either of these games or can recommend them, that would be great too...thanks!
