I heard people go on and on about the SIXAXIS controls in Heavenly Sword and how great they were and when I finally played the entire game...they really couldn't be more wrong.
The part where I had to guide those arrows throw the air was *so* frustrating because I wasn't sitting in the exact right way to make it work well.
The only game I've played (and it was just a demo) that used SIXAXIS well was Folklore. Other than that, I've heard Warhawk is good though I haven't played it.
The SIXAXIS controls in Uncharted and Killzone 2 were just pretty much God awful and a waste of time.
-edit-
Forgot about Little Big Planet.
I think it was neat, but I generally played the game laying down so that meant my Sackboy was always looking down and it was just annoying and pissed me off.
