About 10 years ago it was: "Do girls play games?"
About 5 years ago it was: "Ok, girls play too. But what kinds of games do they like?"
Today it's not about male gamers and female gamers - it's just "gamers" period.
I think we've long passed the day when girls in games were something special, both as consumers and as developers. Many of you may not know, but there are a huge amount of women out there making even the most hard core "masculine" games that you play.
Granted, there are still -less- women in the field than men, but this is evolving constantly - and now especially with the social games boom there has been a huge demand for the female perspective and an influx of women in the industry.
