The NPD results for August video game sales in the U.S. have been released, bringing more good news for the momentum of the 3DS and a gllimmer of light in Wii U software sales. With a number of blockbusters — in particular Madden NFL 25 — arriving, August brought the first year-on-year increase in retail game sales since November 2011.

While hardware was the biggest loser overall, a whopping 40% down over the equivalent month last year, a 1% overall gain was achieved thanks to increases in software and accessory sales at physical retail; Disney Infinity played a valuable role in the accessories results. NPD analyst Liam Callahan, meanwhile, has estimated that physical retail accounted for around half of overall games spending in the U.S. last month, with the overall revenue thought to be a little over $1.2 billion.

Focusing on Nintendo, it's been confirmed that the 3DS is the top-selling piece of gaming hardware for the fourth successive month in the U.S. The NPD software chart, meanwhile, includes two Nintendo exclusives, with all other titles in the chart (with the exception of Minecraft on the Xbox 360) being multi-platform titles. Counting just physical retail sales, Mario & Luigi: Dream Team placed 6th for the month (released 11th August), while Pikmin 3 squeezed into 10th position (released 4th August). Nintendo has also released some figures for these games, with the 3DS title accumulating nearly 190,000 combined physical and digital units, and Pikmin 3 selling more than 115,000 combined physical and digital copies. New Super Luigi U also got a mention, as the DLC release earlier in the summer and the physical standalone version that arrived in August have sold nearly 120,000 copies between them.

Nintendo has also, meanwhile, provided details on nine 3DS games that have sold at least 250,000 combined physical and download copies so far in 2013; details below are for the U.S. only.

No official figures were given for 3DS or Wii U hardware sold, though it's known that the Xbox 360 was the highest selling home console. The presence of Pikmin 3 in the top 10 provides some reassurance, at least, while it'll be interesting to see if the official $50 discount on Wii U hardware, beginning on 20th September alongside the special bundle and download release of The Legend of Zelda: The Wind Waker HD in North America, will bring a bump in sales. Beyond that there are big releases across both the 3DS and Wii U from October onwards.
