A new version of massive multiplayer game World of Warcraft will allow people to change their characters' hair and dance moves, but not their genders. Just goes to show that you can move to a new cyber-world packed with an international population of millions, and still be SOL if you want to find a decent tranny bar. This isn't the first time that WOW has instituted weird, arbitrary rules about sex-related crap, either.
Over the past two years, there have been in-game protest marches and legal action against WOW because Blizzard had shut down guilds that advertised themselves as queer-friendly. And of course, WOW also tries to prevent players from getting into sexual positions with each other, though there are many ways around that.
