Depends. The more actiony RPGs, where a predetermined character has there own skill tree, I tend towards females because they are generally more powerful but fragile, or faster but weaker. And I prefer that playing style. In traditional MMOs, its a pretty even mix. Often times it depends on what name I come up with. In MMO's, well, storyline rarely matters, so I go female because hell, if I'm gonna stare at an ass for hours on end, might as well be a girl.
