for me it usually depends on the game. in games where you can make multiple characters I usually balance males and females and have a male main. In the MMO's that are out again I have a male main and a female alt. In guitar hero ill play as the females though

Im not bi so my defence to playing females is If im going to put 60+ hours into a game why in the world would I want to stare at a guys butt the entire time.......
