I suppose the title of the thread should really be "Worst game of the year - that you have played".
I havent really played a lot of titles this year that have been exceedingly poor. Maybe I've been lucky, maybe I've just been careful or maybe I just havent tried a whole lot of new games.
But Homefront is a 2011 title, right? If so, I suppose that game wins the category. Not a good game, singleplayer or multiplayer.
And MW3 deserves a mention for "least creative game compared to its predecessors"-of the year. Yes, I know its not unique to bash MW3 but maybe it isnt unique for a genuine reason.
Unlike many however, I really enjoyed Dragon Age 2. I wont even stretch to saying it was a poor game. I'd settle with saying that it had excellent narration and a unique story concept(which really didnt fit well for many, as it deviated far from Origins hyper-hyper-hyper cliche that was oh so popular), but of course it had flaws, especielly for a Bioware game.
Shogun 2 should also be mentioned. I might deviate from many other Total War fans, and it should be added that the game had a lot of nice touches that would be awesome in other Total War games. But there's something about Shogun's starved content that to me makes it by far the worst total war game I've played. Maybe I just dont like the setting, but I can barely bother to finish one playthrough.
Battlefield 3 is also turning out to be a growing dissapointment. I like the game in total(except the singleplayer, but im not gonna go yahtzee and judge a multiplayer game by its singleplayer), but the game is gradually turning out to be a bug-riddled unbalanced mess that can even rival the Skyrim patches. Go go origin and battlelog.
