When the Nintendo Wii came out, it set the record for its sales in the first nine months. The Nintendo company now has made a comeback with the Nintendo 3DS, which topped off the Wii's sales with a whopping figure of 4 million consoles.

The announcement came from the company's own website this week, coming parallel to another announcement about Super Mario 3D Land and Mario Kart 7, both of which have also shattered previous sales records in each franchise. Both of these games were the first to sell more than 1 million copies within the United States for the 3DS.

Apparently, consoles with high-end graphics and very strong processing muscle don't appeal to everyone. Games with lower-end graphic requirements, such as those for the Wii and 3DS, always made better sales. This can be attributed to the engagement factor that gets everyone addicted to a game without getting bored.

A game doesn't only need impressive graphics to engage the user. In fact, that's not even a priority for Nintendo, as it has made it obvious time and again through its console design that the company wants to offer feature-rich gaming in an environment that is more engaging.

You might also want to know that the 3DS and Wii haven't really taken the DS out of the scene. The Nintendo DS continues to make a debut in the American market as sales still fly high. In only the last year, the DS made approximately 4 million sales, even with its outdated 2D technology that has been overrun by the 3DS.

The DS still runs at 51 million in its total circulation, compared to 39 million Wii systems, but that can be attributed to the portability factor, meaning that one Wii console can support multiple players rather than only one, as the DS does.
