seems I haven't played long then... I always liked Halo because the multiplayer tends to get really wacky at times. Dropping a tank on someone is always funny
Oh, by the way, the demo version of LFS (
Live for Speed - Online racing simulator) can be downloaded freely and is also playable online... it's a bit limited in content, though. On the other hand, it has the best net-code I've ever seen in a racer; the game's simply designed for multiplayer.
