An anonymous reader writes: Over the years many voices have declared PC gaming dead. We have seen developers abandon the platform for consoles, citing piracy as the cause. Game stores have slowly relegated PC games from prime shelf position to one tucked away in the back corner — even Microsoft dumped AAA PC game developers from the company. It seems though that the demise of the PC as a games platform has been exaggerated, because until very recently sales data ignored digital distribution, with the latest data released by US company NPD revealing that 48% of PC unit sales in the US in 2009 were digital. That translates to 21.3 million games downloaded in the US. Interestingly, while the top online outlet for games is Valve Software's Steam, a large chunk of the sales are one title, World of Warcraft.
