Kotaku have today posted a brief article about the launch of New Super Mario Bros. in Japan.
Sure, New Super Mario Bros. is popular in Japan. But, just how popular? The game moved 480,000 units in its first day, compared to 414,556 units the second edition of Brain Training sold over its first four days. NSMB outsold brain games in Japan. Yes, it is really that popular.
That's quite impressive my Mario Bros. -- the Brain Training games have been wowing the statisticians and now New Super Mario Bros. has topped them!
