this game is really gr8 and the campaign has to be the best halo campaign so far but i dont know if its just me but on the online play on big team battle the lag is terrible. i know theres quite alot of people on but call of duty games seem to be able to handle the massive amount of people, then again it could just be my crumby internet. The graphics on this game are some of the best but again they are overshadowed by call of duty 4, also the ranking system on call of duty 4 is quite alot better because theres more to unlock, theres more ranks to go through and prestige mode makes it fairer on the lower ranked and newer players so in conclusion i think halo 3 is good but cod 4 is better
