As much as it pains me to admit it, I'm not a "person who plays video games". I read about video games. I write about video games. I visit forums of web magazines and discuss video games. I've made small games, and small, silly videos about games. I'm part of the Video Games Voter network, and a member in good standing of the Electronic Frontier Foundation. I don't insist that everyone share my hobby, I don't bore casual aquaintances with accounts of Team Fortress 2 matches, and I'm pretty sure my personal hygiene is up to snuff, but let's face it: I'm a gamer. Games are not a meaningless segment of my life, they're a fairly inescapable and quintessential part of my being, for better or worse.
The good news is that the "typical" "person who plays video games" now looks a lot more like me than the milk-odored stereotype: in their thirties, financially stable, have life will travel. I think, in time, the sterotype will change, probably around the time there's some people on the Senate floor who have actually played Mortal Kombat. "Gamer", good or bad, is likely here to stay.
