New Super Mario Bros. Wii goes quadruple platinum in Japan

New Super Mario Bros. Wii has set a new goal for Wii games to shoot for in Japan; the Nintendo game has surpassed the 4 million sold mark, and that in less than a year. It’s the first game to reach the milestone.

Enterbrain’s figures, as reported by game mag Famitsu (via), put the platformer’s sales at 4,001,276 copies as of last Sunday.

The game also has the honor being the fastest-selling Japanese Wii title ever; it sold over 3 million units in its first 7 weeks.
