Journalist. Preferably a game journalist. Hopefully by then game journalism will have become recognized as a profession, and I can write for an intelligent game magazine/publication/whatever (and still contribute to MyGamer, of course
)
Unfortunately, a lot of the magazine's out there are guys talking like hyped-up 13-year-olds. I have seen a few that talk like an actual person (i.e. Edge, a UK publication), and with any luck, that kind of writing will grow. Until then, I await a video game journalist position as the token female on staff. Yay!
