New Super Mario Bros. Wii tops 4M in Japan, says Enterbrain

Japanese publisher Enterbrain has revealed in this week's Famitsu that New Super Mario Bros. Wii has gone quadruple platinum in the region. NSMBW is Nintendo's first game on the console to achieve that status, having sold 4,001,276 copies as of Sunday. The title will celebrate its one-year anniversary on the market on December 3.

Nintendo financial documents reveal that NSMBW had reached global sales of 16.7 million units by the end of September. That's like, if you're being strictly mathematical about it, nearly triple-quintuple-plus-double platinum.
