What recent AAA title would you consider the most disappointing?
Personally, I would have to say Battlefield 3. The game has been a mess since the official release. Every other multiplayer team based game can manage to put you and your friends on the same team, but for some reason this is too complicated for DICE and Battlefield 3 to comprehend. The sad thing is, even little XBLA and Indie games without the huge budgets and ability to recruit top notch programmers can pull this off. Paying $60 just to join an open beta...
