Nintendo’s video game systems again increased their lead versus other platforms in May, according to the independent NPD Group, which tracks video game industry sales in the United States. The Nintendo DS™ family of portable systems took the top hardware spot with more than 383,000 sold, with sales representing more than 86 percent of all hand-held gaming platform units sold during the month. Nintendo’s Wii™ home console followed at No. 2 with more than 334,000 sold.

Four of the top 10 best-selling games of May play on Nintendo systems. These include Super Mario Galaxy™ 2 at No. 3 with more than 563,000 sold, New Super Mario Bros.™ Wii at No. 6 with more than 183,000 sold, Wii Fit Plus with the Wii Balance Board at No. 7 with more than 161,000 sold and Pokémon™ SoulSilver Version at No. 8 with more than 141,000 sold.

“These May results show that consumers are really responding to the value proposition of our new Wii configuration that now includes Wii Sports Resort and a Wii MotionPlus accessory,” said Cammie Dunaway, Nintendo of America’s executive vice president of Sales & Marketing. “May also saw the launch of two great games: Super Mario Galaxy 2 for Wii and Picross 3D for Nintendo DS. They preface the steady drumbeat of big games for the second half of 2010 we announced at the E3 Expo that will keep fans engaged and having fun.”
