IndustryGamers has another tidbit on the hot sales of StarCraft II: Wings of Liberty since the launch of the real-time strategy sequel. They cite NPD statistics showing that the game not only topped all game sales, but all software sales, saying: "The all categories software PC chart sent to IndustryGamers by NPD reveals that StarCraft II dominated the PC industry for the month, ahead of eight-dollar software like Kaspersky Antivirus 2010, Webroot Antivirus with Spy Sweeper and big name, more expensive software like MS Office. The $100 collector's edition of StarCraft II also placed sixth on the all categories PC chart."
