Hey
So I thought a story may be related to this thread, back in 1995 I used to play in a GW which had a girl who used to come into play, she was nicknamed "ratgirl" for her Skaven army. She had also cool, rat headed Chaos and others... But really she was far more enthusiastic than anybody there, and only after some "guy" continuously hit on her month after month did she quit. She even told him to back off, but after he was employed there it kinda put her off. What I am trying to say is she inspired me to enjoy the hobby as much as I do, even if I never told her about it.
Regardless, I don't think more female models would help market it to more women even if they are less Striperesque. I feel that its quite a niche market and honestly I don't know what will help.
Maybe if people see more girls playing maybe?, though one thing Peterborough's manager would probably put more off than encourage. She certainly made me avoid GW stores for a long time.
