Ok just to let everyone know if you have bought a new xbox (new as in around the time when the halo special editon Xbox came out) it wont work with gamespy or XBC dont know why. BUT IT SUCKS i had to get a used xbox because my first broke so i could play online. AND gamespy wont do anything to fix the problem.
Halo 2 won't be long, so if you can't play Halo:CE online it's not the end of the world. Personally I wouldn't bother with XBC, the lag totally sucks and ruins the game. Play system link for MP, it just rocks more.
