I have COD MWR. I think it is a great game, but you have to really get into COD clans an stuff to get a good COD experience. Least thats my opinion. I love Making Custom Classes (dif weapon sets) going out and having the suspence of being shot at and trying to kill the other players b4 they kill me.
So COD can be fun you just have to open yourself up to the different experiences the game or (any game for that matter, has to offer)
And COD MWR too me has great online game play.
