His arms must be getting tired after all these years of profit

The independent NPD Group recently assessed March U.S. gaming sales, placing Nintendo systems and games at the top of the list.

The DS/DSi and Wii took the top two spots in platform purchases, moving 700.8K and 557.5K units respectively, with Sony's PSP system selling a comparatively unsubstantial 119.9K units. The Xbox 360 and Playstation 3 hold the third and fourth spots with a thinner margin betwixt themselves and the Big N, the two selling 338.4K and 313.9K units each. According to a recent press release, these DS/DSi sales are the best of any portable system in the month of March.

Games on Nintendo platforms took four of the top ten spots in U.S. sales as well in this past month. Pokémon SoulSilver and HeartGold placed first and fourth with 1.02M and 761.2K units each while New Super Mario Bros. Wii ranked at number five (457.4K units) and Wii Fit Plus with Balance Board came in at six. Battlefield: Bad Company 2 (Xbox 360, Playstation 3), Final Fantasy XIII (Xbox 360, Playstation 3) and God of War III (Playstation 3) filled out the remainder of the top five.
Nintendo's press release is as follows:

Nintendo DS and Wii System Sales Back to Top Two Positions in March
According to the independent NPD Group, which tracks video game sales in the United States, the Nintendo DS™ family of hand-held systems – including the new Nintendo DSi XL™ – set an all-time record for portable system sales in the month of March, selling more than 700,000 units nationwide. Sales of Nintendo’s Wii™ console reached nearly 560,000 in March as post-holiday inventory began to improve. Nintendo systems accounted for 59 percent of all video game hardware sold in March.

“Demand for Nintendo fun continues unabated,” said Cammie Dunaway, Nintendo of America’s executive vice president of Sales & Marketing. “We’re glad so many people are able to get their hands on our systems as we prepare for the May launches of Super Mario Galaxy™ 2 for Wii and Picross 3D™ for our Nintendo DS systems.”
Four of the top 10 best-selling games in March play only on Nintendo systems. These include Pokémon™ SoulSilver Version at No. 1 with more than 1.01 million units sold, Pokémon HeartGold Version at No. 5 with more than 761,000 units sold, New Super Mario Bros.™ Wii at No. 7 with more than 457,000 units sold, and Wii Fit Plus™ with Wii Balance Board™ accessory at No. 10 with more than 339,000 units sold.
