Don't mean to be a Valve fanboy here (even though I am) but you wouldn't see this at a convention around a Valve game.
Look at i46 for a second, it's just lots of people chillin' and hangin' out, playing some video games. No fancy lights or hookers. Just video games. And it's them that's leading the current games world. From TF2 competitive gaming to the Dota 2 internationals and to just plain playing their amazing games they ARE leading the gaming future to a better place. I've noticed more and more people at school are starting to know about Steam and it's really awesome that that's happening.
Valve and indie games = my hope for a better gaming future (as well as a couple of other companies)
