In a statement released following this month's NPD results, Microsoft declared that November 2009 was "the company’s best-ever November for [U.S.] game sales," with $514 million in Xbox 360 game revenue.
Combined with hardware and accessory sales, which contributed an additional $324 million, the month was also deemed to be "the best November in Xbox 360 history" overall.
A significant part of that was the overperformance of Infinity Ward's Call of Duty: Modern Warfare 2 on Xbox 360 versus PlayStation 3, with the Xbox 360 version outselling its competitor by 2.25 to 1. This corresponds to 4.20 million units on Microsoft's console compared to 1.87 million on Sony's.
Along with games like Assassin's Creed II, Dragon Age: Origins, and Left 4 Dead II (which, with the exception of the latter, also released on PS3), Microsoft said that third-party games sold more on Xbox 360 in November than on PlayStation 3 and Wii combined.
The company also said its Xbox 360 Modern Warfare 2 Limited Edition Console "flew off store shelves," but did not break down Xbox 360 sales between that package and other available SKUs. NPD's reported sales of the game do not included bundled copies.
Finally, the company boasted that players spend more than 5.2 million hours playing Modern Warfare 2's multiplayer mode on Xbox Live during the game's first day of availability.
