New Super Mario Bros. 2 for the Nintendo 3DS features a strange concept. It's a game about, primarily, collecting gold coins. In fact, Satoru Iwata, President of Nintendo, had Takashi Tezuka explain what it is that makes New Super Mario Bros. 2 so unique.

It's the coins. The lengthy interview above goes over all sorts of details for the title, but Tezuka initially explains that the core concept behind this game is collection 1,000,000 coins. The gameplay has been modified so that's possible.

New Super Mario Bros. 2 will launch for the Nintendo 3DS sometime this fall.
