It's a funny thing. In my part of the videogame business there are tonnes of women. But, I could count on one hand the number of girls I've met testing games. Again, a chicken and egg problem. With hardly any women in the industry the arrival of a genuine female means that she is instantly a nexus for attention. Whether it is the well meaning kind of "Oh you're a girl so you must be struggling to integrate." to the more negative, slobbering, "I can't wait till we all get drunk at the Christmas party so i can book myself a trip to HR." sort. Either way, it makes you stand out as being different.
Much as I would hate for it to happen to me, I do honestly believe that forcing the number of women in the industry to be higher by the application of quotas would be an effective means of redressing the imbalance. Once having a number of girls in the office becomes the norm, the novelty wears off so that girls are not made to feel uncomfortable by default, so more games will be made by people who think like girls, and more girls will want to get into the industry...
At least, that's what would happen in an ideal world.
