I feel the same about gears as all of you. Also:
Perhaps Star wars: kotor. It must be said that I got to play the game late, like when the 360 had been around for a year. But anyway, I understand how people can like it because you can be what you want, you have a pretty good sense of freedom, the story is well handled, and you can choose whatever you want to say to everyone. But for some reason I didnt enjoy it. I found the combat a little boring and lost interest in the story after a while. And I found the framerate to be a bit of a *****. :/ Same goes for morrorwind. I guess I easily loose interest in games with a lot of freedom.
I also didnt enjoy okami that much. It was very original and thats something I really like, but I got kind of tired of the waggly combat on the wii, and the lack of puzzles that required as much thinking as regular zelda puzzles.
Last: super mario galaxy. Its a superb and polished game in so many ways, but for some reason I didnt enjoy it that much. Perhaps the game worlds was a little too linear (without secrets to find), and a little too easy. I would still rate it as one of the best games ever though
edit: and the rts genre in general.
