Re: Cross gender game play.
Write your character as a person. That's the "secret" to playing or writing someone as the opposite gender from yourself - great them as a person. Hopes, dreams, pet peeves, fears, goals, interests, and so on - women and men share these all in relatively equal measure. Do not look at gender stereotypes (they are, in fact, pretty dang awful and largely rooted in current social constructs) and don't believe in any artificial limits.
