It wouldn't be a big surprise if Halo: Reach was the No.1 title on Xbox Live during its launch week. It's a big-ass game after all. But that was not the case, as some corrected numbers show.
Yesterday, Xbox Live community guru Larry Hryb - Major Nelson to most folks - published the weekly list of the 20 most popular titles (according to unique users) on Xbox Live, showing Halo: Reach at No.1. Today, the Major discovered he'd made a maths goof and corrected the list: Modern Warfare 2 was in fact the most popular game during Reach's launch.
Hyrb notes that Halo: Reach, which released on Sept. 14, was available only six of the week's seven days. However, Halo 3 was in third place.
(I note that eight of the top 20 are either sports titles or demos, including the FIFA 11 demo at No. 5 and, notably, the Pro Evolution Soccer Demo at No. 19.)
For its part, Bungie posted its own set of numbers this afternoon - showing more than 70 million games have been played, 20 million daily challenges have been completed, and 5901 years have been spent in online games. And, "our sources tell us that we've been the number one title on Xbox Live for the last seven days."
