Both my mother and sister are die hard RPG fans =)
Although we don't have the netspeed to play MMORPG's, they are dieing to give them a go.

I would have to say that the main difference between male and female gamers is the want for a reason. Most guys will be happy to 'frag' countless AI in the name of fun, but it isn't that simple for a lady.

Brings to mind a joke I got told by my grandad:
Doctor says to a family; "I'm afraid he's going to use a brain transplant."
The doctor continues to say; "Sadly, it is not cheap, a male brain will cost 10,000... or 2,000 for a female brain."
Shocked the family stays silent untill a guy finally pipes up to ask about the price difference.
The doctor replies with a smile; "Well, it's because of the marketplace, we have to sell brains that have been used at a lower price"
Jokes aside, you are far more likely to find a lady playing an RPG then a FPS, although I'm willing to bet this is no surprise to anyone here...
