Greg Street, lead systems designer for World of Warcraft, can scarcely contain his excitement. When I called him to discuss the game’s upcoming Patch 4.3 with him last week, I half expected to sit through 20 minutes of dodgy answers and vague generalizations. Instead, Street spoke with the intensity of a man who has withheld a secret for far too long, and I half worried that his superiors would wince at the details he poured out throughout the call. Even Shon Damron, a member of Blizzard’s PR team who also sat in on the call, was barely able to get in a word. It was, all in all, an infectious passion, and one that left me feeling more excited about the game than I’d felt in years.
