The Player's Journey
In response to Keith Campbell's question on his blog, I consider myself a "player who plays themselves," meaning, I am likely to play with the attitudes and ideas that I personally have. Allmost the entire class considers them themselves the same way as well. We probably are more inclined to think like this because of the many choices games now present to us. We can get more involved with our character in Oblivion, than in Pac-Man.
You brought up a good point regarding the many choices available to us now in games, especially in RPGs. It is easy to model our characters after ourselves and not just to looks but to actions as well.
