The graphics in Call of Duty suck in general, and since they make a game every single year, they have no chance to make a new engine. I think they should take two, or even three years off from releasing stupid games and release one final, good game. However, if a new Rainbow Six Vegas comes out before they do that, well then Infinity Ward and TreyArch can suck each other off while I play an actually good game. And what I don't understand about the CoD series is how people seem to forget the first Call of Duties, they were incredible. You know, I even loved the third one (although no one else will admit they do) better than the knew ones. The single player reeled me in emotionally and I had fun, and I can still go on and find multiplayer matches today.
