I also only play female if the male version looks stupid, Mass Effect is a good example, male shep is just that stereotypical bald spacemarine-type.
oh and most game-characters with my favorite class 'rogue/archer' are female
people who say "you should only play male because you're male" are stupid imo. Isn't that the idea of videogames? to play stuff you normally couldn't? being a stealth agent as sam fisher, a professional race driver, etc. or in this example, playing as a female.
