Alright i played Doom 3 and the online Co-Op. let me tell you one thing. if Halo 2 would of been like that with online Co-Op with that bad quality then im actually glad Halo 2 came out without it. The Doom 3 Online Co-Op is bad. I bought there limited Edition aswell and that was certainly not worth the 60 i payed for. I Still consider Halo 2 way better then anything out there for the Xbox. Next to test would be Half-Life 2 but they are saying that wont come out for this Generation Xbox but for the Next, who knows it might even be good. Halo 2 is still undoubtably the Winner in this. as far as Online Co-Op goes, thank goodness they chose not to implant it into Halo 2. I dont think its meant for this generation of Consoles. bye all
