Here are some unrelated gender based observations.
I have been lucky enough to game alongside 23 players in my gaming lifetime. Of those 20 were men and 3 were women.
I have glanced at some of the fantasy rich ‘fandom’ peer groups and there is see an almost 50/50 or maybe even female dominant population, people like your Whovians and Pottermores to name but two.
As far as I am aware there are no female developers on the RMU dev team although I could be wrong on that.
