The NPD Group reports on three different categories of videogame revenue every month: hardware, software and accessories. Hardware and software represent game consoles and games respectively, while accessories represents everything from controllers to peripherals to Xbox Live cards.
Today, NPD reported that, while both hardware and software dropped for the month of September as compared to the same period a year ago, accessory sales were up by 13%.
The #1 selling accessory for September was, once again, the Xbox Live 1600 point card, followed by the $20 PlayStation Network card. Additionally, the PlayStation Move, which released on September 17th, was also among the top-ten accessories for September in the form of three separate SKUs, including the Move + Sports Champions bundle.
