FPS Games, because most of them feel extremely repetitive to me. There are exceptions like Bioshock (dem gaem was amazing dood), an for some reason i had a lot of fun with the F.E.A.R Series, but aside of those, i neither get satisfaction nor plain fun out of most them. Other games unravel more and more kinds of gameplay as you progress (or just give you a good story that keeps you intrigued), FPS's's..(ssss?) lacks that. big time.
