Prince of Persia: Revelations
Why is the warrior within so surly?
Seriously, though. If you're going to port one of the console Prince of Persia games to a handheld, why choose Warrior Within? The red-headed stepchild of the modern Prince of Persia series was not only super-buggy, but featured an easy-to-hate hero (viva generic rage!) and fighting-centric gameplay that turned off most fans of the first game.
And Revelations - which is basically a director's cut of Warrior Within - has all of the same problems, with the added bonus of clunky camera control thanks to the limited inputs of the PSP hardware.
