The NPD numbers for December 2008 and the overall year are in, and among the many other best-selling Nintendo games is the three-year old Mario Kart DS. The portable game was the eighth best-selling game last month, and the tenth best-selling game of the year. This thing is three years old! How is that possible?!
Mario Kart Wii was number four in December and number two for the entire year. Surely sales of the DS game were encouraged by the popularity of the new Wii edition. The portable game sold over half a million copies in December, which was a third of its total sales for the year.
Mario Kart DS has now sold a total of 4.3 million units in the 38 months of its life.
