Best games: CoD 1 to CoD: WaW. Worst games in CoD history: MW 2 & BO. Best Battlefield games: BF 2, BC 1 and BF 3.
Get rid of the lame, lewd and crude advertising. It makes me want to boycot both Ubisoft and GameSpot.
Who cares about the engine, most only play Call of Duty for it's multiplayer which kicks Battlefield's butt!
CoD's screwed this year. from this to the extreme lack of advertismants and good interviews and the lack of a new engine and new gameplay. Battlefield 3, however, is going to be amazing :)
Oh, and Activision had this problem coming since they just won't seem to change the engine and gameplay
