Cod 4 had an INCREDIBLE story, cod 5 the single player is more replayable and varied but the story was BAAAAAAAAAD. It was just goin around and takin over japanese islands then fighting back for your city in russia then going apes**t on the germans.. MW2 looks to have a F**KIN AMAZING story tho
COD5 and 4 were sorta even story mod for me but i picked COD5 because the Zombie Mode!! But COD4 WAS WAAYYYYY better Online!!!!!!!! Unrelated to the topic but The best game i have evr played for the Story Mode was Metal Gear Solid 4!!!!
