Downloads account for 5 percent of New Super Mario Bros. 2 sales in Japan so far

Nintendo's digital distribution scheme for retail games has had a relatively slow start in Japan. Nintendo president Satoru Iwata told the Wall Street Journal that digital sales of New Super Mario Bros. 2, which was released in the region on July 28, have made up 5% of the total. Iwata seemed all right with this result: "This initial offering going forward, we've gotten a good reaction going," he said.

The other new retail/digital game, the Brain Age sequel Demon Training, has sold approximately 20% of its total audience digitally. Iwata believes the reason more people opted for the downloadable version of that game is the convenience of playing the daily challenges without swapping cartridges.
