A Microsoft representative told Shacknews, "There was a manual error in reporting Xbox Live data for the week of Sept. 13," confirming that Halo: Reach was the number one game on Xbox Live for the past seven days and had "nearly four times as many unique users playing the game on Xbox Live vs. Halo 3 for the week of Sept. 13."

At TGS 2010, Microsoft's Phil Spencer announced Halo: Reach had generated $200 million in sales in its first day of availability, revealing the title also broke the previous record of simultaneous users on Xbox Live. Following the Live Activity posting for the week of September 13, Shacknews contacted Microsoft to confirm the numbers were accurate.

The representative said a corrected list for the week beginning September 13 will be published which will feature Halo: Reach in second place between Modern Warfare 2 and Halo 3, noting that Reach was only available to consumers on September 14. [Ed. note: The listing has now been updated.]

The complete quote from Microsoft regarding the Halo: Reach Xbox Live debut can be found after the break.

There was a manual error in reporting Xbox Live data for the week of Sept. 13. "Halo: Reach" was the number one game on Xbox LIVE for the past seven days and had nearly four times as many unique users playing the game on Xbox LIVE vs. "Halo 3" for the week of Sept. 13. A corrected list is being published which will show "Halo: Reach" as the number two game on Xbox Live for the period of Sept. 13 - 19 (having only been available from September 14th onwards), followed by "Halo: 3" in third place.
