My brother and I have been playing some games of Civilization: Revolutions on our PS3s. It's fun. One annoyance I have: The AI's usually not much of a challenge in the long run. About the only problems I have with 'em is maintaining some defenses in the early game while the computer sends in legion armies. I've heard it gets them for free at times.
So, anyway, my PSN ID is BronzeDog (no space). Feel free to drop friend requests. We can also talk other multiplayer games if you like. Of course, we also have Civ4 on our laptops, though fair warning: My brother's tends to overheat and shut off. He's got bad luck with laptops.
