Mine would Batman Arkham City. It's nowhere near the incredible genuine Batman experience that was Arkham Asylum.
Have to disagree with you there, thought Arkham City was a great game. Easily one of my favourite games of 2011. Back on topic, Uncharted 3 was disappointing. Mainly on the multiplayer side, single player was ok but nowhere near as good as Uncharted 2 in my opinion.
I can't think of any dissapointing game of 2011 that I actually played... But if I can mention a game from 2012, Max Payne 3 really dissapointed me. It was asbsolute garbage! That was 500 kr. (about 85$) out of the window
I'll say Skyrim. I enjoyed it but to me I felt that the quests in Skyrim were not as good as Oblivions. I didn't enjoy the main quest, infact the ending made me feel so disappointed. UC3 had the same but it had some redeeming value with its ending.
I would say L.A. Noire. It's an interesting game with a pretty good story but had a lot of flaws gameplay wise. The investigations felt that they had no merit as you could easily replay them. The interrogations felt awkward as hell as the three choices: Truth, Doubt, and Lie were all extremely vague. The open world aspect felt pointless and empty. In the end, L.A. Noire's story could not make-up the fact that the game did not feel very rewarding and immersing.
Considering that I don't buy a lot of new games, this one's a little tough for me...but if I had to choose, I'd say Resistance 3. An overall good game, but too many sections felt needlessly tedious for my liking (PA maze in particular.) There's also a huge story gap from PA to NY that irks me...
Co-op Adventure Tips & Tricks and Amazing Lab Idea- Now with Brackets Mentioning Kudos Count!
Dragon Ball Z: Ultimate Tenkaichi let me down.
Still an okay game and fun to play, but I was expecting it to be a lot like the Budokai Tenkaichi trilogy, which I had loads of fun playing when I was younger. Definitely not worth the forty bucks I paid, but it's not terrible.
