Hmm, tough choice...
most probably the Prince of Persia. He's witty, can run on walls and do flippy stuff, is a good swordsman, and controlling time is awesome. The whole thing with the Dahaka and the Isle of Time would be kind of rough, and the Dark Prince, but after that, I'd get to be King of Persia and have Farah. Sounds like a good ending to me! 😄
