@op: let me guess, you mainly play FPSs? (with that setup, its kinda obvious)
if you do, then your sentiment does not surprise me. FPSs have just been regurgitating the same shiz over and over again.
go out and buy a nice RPG, something that gets you involved, that makes you think, grips your soul and doesn't let go to the point where all you do all day is think about how to tweak your character. doesn't even have to be a new game, there are a lot of good games out there.
i haven't touched an FPS since playing HL2 3 years ago, aside from Borderlands because i like loot-whoring.
