It was another relatively slow month for video games sales, but Nintendo's handhelds bucked the trend.

Anita Frasier, an analyst for U.S. retail tracking firm NPD, said,  “Of the hardware platforms that were on the market last July, only one, the 3DS, realized a unit sales increase over last year.  Both the DS and the 3DS, however, realized a month-over-month unit sales increase over June 2012 while the other platforms declined.”

Physical game sales were down again, with a total of $260.7 million (compared to $338.5 million in 2011). NPD estimates that an additional $117 million was spent on physical product in the form of used sales and game rental. On the digital side, a total of $439 million was spent on downloads, microtransactions, mobile apps, and social games.

While the top ten games below is based on the total of the sales for all systems a game was released on, NPD said the high selling individual SKU was Nintendo's Pokemon Conquest.
