While self-expression (or obstacles thereto) undoubtedly figures into my situation, I see it more as a consequence than a cause. Primarily, I identify as female because I cannot relate to male social conventions, feel more calm and relaxed when I think of myself as female, have to suppress feelings of panic when using a group shower in a men's locker room unless I am alone, and feel uncomfortable with seeing a male body in the mirror every day. I don't know if I would ever want to bear a child or not, but I do wish the choice had not be made for me before my birth.
On the subject of transgender geeks, I have found that geek culture is generally rather open-minded regarding matters of self expression and self identity. This, no-doubt, provides closeted transpeople a much more friendly environment in which to come out. Just look at all the gender bending that occurs in science-fiction, fantasy, and anime/manga books, videos, and games. It is not unusual to find cisgender and transgender crossplayers (cross-gender cosplay) at conventions for these genres, especially anime/manga.
As to World of Warcraft and the like, this is one geek (and a computer geek at that) who finds computer games mind-numbingly boring. I'd much rather play "pen and paper" RPGs, Scrabble, Eurorails, Fluxx, Poker, or even Dominoes than a computer game. I don't see anything wrong with computer games, I just don't get any enjoyment from them.
