You might be a Video Game Wanker.
Funny article on Sarcasticgamer.com about video game culture:
From the post: "There are things that people do within any sub-genre of popular culture that annoys the crap out of everybody else. These people are Wankers. People that act overly important about trivial things, say or do idiotic things in the name of their favorite pastime/hobby, etc. Like the overly enthusiastic semi-pro jock at the company picnic, your buddy that thinks of themselves as a film auteur, and even calls Citizen Kane “their favorite movie” or even the emo kid down the street that hates you because you love Rush in a non-ironic way.
We have these people in video gaming as well, I posted some of these on Twitter and got some hilarious submissions from other Tweeps, read on!"
