Deadly Premonition (Xbox360; PS3 only available in Japan, with an optional English voiceover)
Not without a reason, this game polarizes heavily. And actually, after 2 or 3 hours into the game, I wasn't too fond of it either. The controls are bad, and by that I mean really, REALLY bad. The graphics are more than outdated and all in all there's a lot that you need to get used to.
But once you let yourself engage in the scenery, you probably never want to leave.
It is an open-world, mystery solving survival horror game with third person shooter elements. It references all kinds of popculture classics like Twin Peaks, Ju-On, Jacob's Ladder and what not, and is accompanied by a wonderfully catchy, and seemingly random, choice of music.
On top of it all, with its charmingly offbeat sense of humor, it manages to generate a truly unique style and atmosphere. Not a single other game surprised me as often as Deadly Premonition did.
If you want a weird and lovely fucked up experience, and can actually live with bad controls and graphics, I would definitely recommend it.
