The lights are on
While metro is definitely more closed in than typical BF fare, it's understandable as it's infantry only.
That being said, it's had it's share of bugs (the most annoying being players hiding under the map), but I trust DICE to fix these before the final game.
My only real complaint is with EA, who has deemed it fit to force PC players to install spyware to play the game. Thanks to that, I chose the 360 version. However, if EA changes it's policy in that regard, I will be picking up the 360 and PC versions.
