And for a guy who's created everything in this gigantic universe, he's remarkably "geeked" about it -- he still talks like he's a guy sitting at his basement table creating D&D quests (which, don't lie now, we've all done at one point or another). The second part of the interview is even more interesting -- Metzen talks about his creative process and just how much of a group process it is at Blizzard. Since they're all in the target audience, every group member censors each other and pushes each other to bigger and better heights of storytelling.
Metzen also mentions a non-Blizzard project called Soldier: 76, about a guy making his way through a second American Civil War. It came out a while ago, apparently, but would definitely be interesting to see what Metzen does outside of Blizzard continuity. And as if there was any doubt that Metzen was a rock star, he ends the interview exactly the way you'd expect a creative superstar to end it: when "you've tapped into something beyond the individual," then "it's off to the races."
