I played RF2 the other day, and holy shit, the gameplay feel is absolute crap.  None of the weapons feel dangerous, it takes like a full clip to kill an enemy no matter what gun, and the enemies aren't affected by the bullets until they finally die.  It just feels fake, for lack of a better term.  It has that one gimmick of being able to blow through walls, but the rest of the game sucks.  The one thing I did like was the speeches and music in the menu, really gave the feel of a revolt in russia.
