I actually really liked Prince of Persia 2008 - the visuals were breath taking and even though it was a fairly short and repetitive game, I still had a lot of fun with it.
Sands of Time was awesome, and the Warrior Within sequel was also really good except the god awful music. The Two Thrones was great except for that weird bipolar thing (though I'll admit playing as the Dark Prince was actually super fun) and I really liked the continuous, linear world design. Never played any of the future 3D Prince of Persia games.
Bring it on, Ubi!
