Gran Turismo 5.
I had heard the bad press. I knew the menus were bad. But I didn't expect... I mean, I thought the core game would still be good. :(
Also, Flower. That is not a good game. The 6-axis controls were not okay. You don't get away with bad gameplay just because you're pretty. I really wanted to like it, too. I was excited to play it when it first released.
Regarding L.A. Noire, that game is special for me. It is one of the very few titles that I love and will readily admit that whole parts of it are pure and absolute festering garbage. That the very foundation of parts of the game design were deeply flawed. Even so. Still love. ...oh god the bulldozer chase. oh god. D':
