I don't think the game is awful and everyone is entitled to their own opinion but I don't see any way a gamer could have enjoyed the Bulletstorm campaign more than say, the Bioshock or Call of Duty 4 campaigns. Not to mention the Halo games, Borderlands, KZ series, BF:BC series, Resistance series, Condemned, FEAR series, Half Life 2 and it's expansions, etc, etc, all of which are this gen FPS games.
Strong statement from Buzzman considering the overall quality of FPS games this gen, but again, everyone is entitled to their own opinion.
