Backbreaker Vengeance: Too Expensive, no real way to have a 2 player vs match with one tackling and the other dodging. (Still fun though)
Sam & Max: Season 2: Frustrating puzzles that require you to mindlessly click on everything
Magicka: Still buggy after months, highly complicated controls.
L.A. Noire: Much Trial & Error without the "Trial", Street Crimes start to get annoying
Dungeon Siege 3: Jeyne Kassynder is bland. Also, Jeyne Kassynder is fairly boring as a main villian. And you only get to see Jeyne Kassynder at the end of the game, save for 5 minutes in the middle. Also, everyone in the game says Jeyne Kassynder A LOT, so that you get annoyed by the mere mention of Jeyne Kassynder. Also horrible Co-Op Camera
Half Minute Hero Super Mega Climax: Xbox Controls kinda suck, could use more initiative for the player to do the additional challenges since the core game is fairly easy by concept.
Battlefield Bad Company 2: L....ag. Also i suck
