Saints Row 3, I heard great stuff about it but it kinda just bored me.
The Simpsons Game, I loved Hit and Run so I couldn't wait for it to come out, but it was finished in a couple of days and didn't have much replay value. I wouldn't mind picking it up and playing it again now though.
Mafia II, I freaking loved the first one (PS2) but it didn't have the same charm with Mafia II and it felt much shorter. Also the reports about how half the game and all the side missions had been cut really annoyed me, even some of missions they shown to advertise the game were not in the final product.
I just thought of one of the worst games I ever played... Super Trucks Racing for PS2. I love semi trucks and racing games, so this game is the perfect combo for me right? Wrong. The game is horrid with glitchy controls, cheat codes that don't work, confusing layout if you are using a regular controller, and every track is a road course and I suck at road courses. the only oval track you have to unlock it and if you try the cheat code, it doesn't unlock it. There's a reason this game was packaged in bundles
