It's telling that Microsoft put a tester in charge of Halo 3, a game that it has to get right. Bungie's Harold Ryan said eliminating bugs is especially important with a game such as Halo "that sells 8 or 9 million units or something."
"With 100 testers in the building, [if] you can find a bug one time, 8 million people are going to find it a hundred or a thousand times a day," he said. "In my opinion there's no room to let that bug you only find once go, and that's really the model we follow. We have a system that logs every single crash the game ever has and we investigate and fix all of them."
