Ryan found himself at the center of two of the biggest vidgame stories of 2007.First, the head of Bungie Studios saw his company’s “Halo 3” break records by grossing $300 million worldwide in its first week. A few days later, Bungie shocked the biz by announcing that it was leaving parent company Microsoft. “It got harder over time to retain Bungie as a place where top creatives would want to work,” Ryan says of the move. In an industry where successful development studios invariably get bought by publishers, Bungie is bucking trends in a big way. But it’s in the enviable position of having Microsoft as a minority owner and three hit “Halo” games behind it, which Ryan says provide a very solid financial footing.
