Of course, the "you" there is you, not a universal "you." I agree, though, because any game where you generate the full facial features, attributes, and personalities of a character is clearly allowing you to create a new "you". It might be wildly different from who you are, but it is certainly a representation of who you are in the context of that game.
Also, I wish I could identify with Ratchet. Because I want a gun that turns monsters into exploding giant chickens. And a cute robot sidekick. And to freak the fuck out of my cat.
