having just played a few hours of sp and mp i would have to say that COD4 is a much better game. The combat is more intense and the story is a hell of a lot better than halo. The graphics are much better than halo and different types of levels you can play are very well done (sniper level, the helicopter level, etc..) Great game that everyone should get. The mp is also very well done and i will continue to enjoy this much longer than i played Halo 3 mp.
