Best Games For Mac

Back and college, my friends and I used to do the whole Age of Empires thing in the dorm. We always had a good time, so now, a few years later (damn, I hate getting old), we'd like to start playing again. However, my friend, being in graphic design and animation, is a Mac user. That's fine, whatever works, but we're looking for a game that we can each play. We both put our hands on a copy of Age of Empires III, and got set-up to play online, only to find that it didn't support cross-platform play.
So do we have any options? Real-time strategy was always our favorite, AoE, C&C, etc.
