Some XBOX 360 Sales Figures
Major Nelson has posted figures regarding XBOX 360, Halo 3 and Mass Effect sales on his community blog. Microsoft has sold more than 17.7 million XBOX 360 consoles worldwide. Over 8.1 million copies of Halo 3 have been sold since its launch in September 2007 and Mass Effect reached 1.6 million copies sold in six weeks.
So from those figures, nearly half of XBOX 360 owners own Halo 3 and almost one in every nine XBOX 360 owner owns Mass Effect!
