And frankly, if a transgender player were told something along the lines of "the rules allow you to begin the game as whatever gender you choose, ...." they might find that, well, enlightened, perhaps, and may react positively to a game that treats changing gender as no big deal. Can't be sure, of course, being decidedly single gender myself, but I speculate that it shouldn't be an issue unless one's group is overly puritanical (and I don't suspect Munchkin would be the most popular game amongst groups like that.)
