Nintendo's New Super Mario Bros. Wii has sold 3,002,753 units in Japan, becoming the fastest game ever to reach the 3 million mark in that country.
It accomplished the feat in seven weeks, says a Famitsu report translated by consumer weblog Kotaku. New Super Mario Bros. Wii launched in Japan on December 3, 2009, and had the biggest-ever debut for a Wii title.
At that time, the title sold 936,734 units in its first week in Japan -- the biggest debut to date for a Wii title in that country. NSMB Wii even outdid Nintendo's previous first-week sales champion, Super Smash Bros. Brawl, which sold 816,000 units in its debut week.
Although Infinity Ward's Call of Duty: Modern Warfare 2 broke global sales and revenue records for the year, analysts like EEDAR's Jesse Divnich have suggested that, over its lifetime, New Super Mario Bros. Wii will eventually surpass that title.
