From the article: "Don't get me wrong, sales data is great, and I always love pouring over the monthly NPD reports to see just how much more money Nintendo has managed to print; and when I hear that World of Warcraft has passed the 11.5 million subscriber mark, it certainly makes a mental impact. But the questions always remain: "When people bring that Nintendo Wii home, do they actually play it?" "Just how dedicated are these WoW players?"
Thanks to the Nielsen ratings, which measure usage for the Top 10 PC titles and all major consoles, partial answers to both those questions and more await you after the break."
