Also, I don't think the sex of a character hardly matters. Is the main character male or female? Why would that lesson or increase the appeal of a game? We've had our fair share of games with main/major characters of both genders.
As an experiment I played WoW as a female to see how different I would be treated, and I'm still like WTF?? Its really us men that are always bringing up the gender debate.
Women are just people like us men
Everyone kept bowing, and blowing kisses at me - doing all sorts of antics to get my attention. What person male or female wants to deal with that crap going about their business.
There's a flip side to this coin though, which is that I had people doing things for me that encourages being lame. One guy I did a 'brb' with just to see how long he'd wait. I used the bathroom, made a sandwhich, watched a show, came back and he was still waiting.
Further, all the noble talk is also rather pathetic. "I'll always be here", etc... etc... If I were girl, every online game I play I'd play as a guy. The favor slave aspect is nice, but thats about the only perk
