I think call of duty in many ways makes sense when viewed as a singleplayer game (which in recent years it hasn't been). When I buy it, I am not looking for "innovative gameplay, etc". I am instead looking for the gaming equivalent of a Movie. I typically like the story, and with around 6 to 8 hours of gameplay this works out to around 4 movies which is coincentally about the same price when viewed in terms of tickets.
