I wouldn't be into it too much - I don't really have a great deal of attachment to my appearance - it's not that I'm unattractive or anything, I just don't really care, and don't really see it that often because I don't usually look in mirrors. With good character creation options, its possible to make many faces which I would find much more interesting.
Moreover, I don't really care for the idea of LITERALLY playing as myself, because by the very nature of the game, I'm limited in what actions I can take as the character, so as far as I'm concerned, the character isn't me, it's a character who looks like me, which, again, I don't find all that interesting.
