I prefer Call Of Duty World At War. I think Treyarchshould have just stayed with the World War II genres. They are more funner to me because you are fighting in some of the most important battles in history.
i like COD 5 but COD 4 is better because you can get camo on the guns and the guns are better. i also like the more modern playing style. i cant wait for COD 6 to come out
