According to the NPD Group, online-capable games sell more on Xbox 360 than any other console.
Xbox 360 sold twice the amount as PS3 last year, and battered Wii seven times over. The NPD didn’t give sales figures, however.
Xbox Live cards sold four times the amount as PSN’s, and both platforms basically destroyed the Wii. As for currency sold through the services like Microsoft points, those weren’t taken into account.
