World of Warcraft
I'd like to clarify the whole all girls who play WoW are fat and ugly and easy. I'm a girl that plays WoW I'm NOT fat nor am I ugly. WoW is one of the most addictive games online, taking up a lot of your time and money.. and friends. It is also one of the most wicked awesome games ever invented. With the exception of soulbound items and such it is definetly better than, dare I say, Halo.
Most of the girl characters on WoW are actually guys that are complete pervs with nothing better to do in life but watch an animated girl run around and hack at things with her sword while dancing like a complete whore. But the rest of the girl characters are actually girls playing WoW, most are fat and ugly but you will find the rare awesome looking one that looks just as hot as their computer animated character.
