Diablo III launched today after years of development and anticipation, and our friends at Polygon have been hard at work in the demon-killing business since the wee hours of the morning. But they're still going strong in their quest, and you can hop on over to watch them play through the game via their Twitch TV livestream (spoiler alert: you'll be watching the later stages of the game). Be sure to join in soon, since Polygon will be giving away a copy of the game to one lucky audience member sometime in the next half-hour.
