Ikaruga

I don't mean to be repeating myself, but I just got Ikaruga, and it's awesome. The polarity system adds even more strategy and challenge to a genre known for it. The game is made by Treasure for gods sake. If you have a 360 do yourself a favor and go try the demo at least. I just cannot recommend this game enough for other shmup fans like myself. Awesome style, responsive controls, its always clear where you are, amazing co-op, a very skill based point system, and extreme difficulty. All the things a great shoot 'em up should have. ; )
