I wish the gaming demographic was like what you see in magazine ads, the few gaming tv commercials there have been, and the "examples of play" found in several RPGs....an even mix of girls and guys. Unfortunately, it's not.
In the 18 years I have played (started when I was 11 or 12), I've pretty much kept with the same core gaming group - with a couple of players coming and going during that time. We've only had two girls that were ever interested in joining (even though we have all tried, at one point or another, to get our significant others to give it a go), and they were great players.
Travelling to various game stores on game nights, talking to people at conventions/school/work, and sharing stories with other gamers - I have just accepted that there are a lot fewer women in gaming than men. Like I said, I wish the demographics were different. Maybe then, the stereotype would change, and the attitude directed at women who DO play RPGs would change especially women that are *gasp* attractive, and[/] who play RPGs.
