There's been some debate recently over just how big the market is for downloadable PC games in comparison to copies sold in retail stores. One study said downloadable copies of PC games have almost caught up with retail sales while another stated that retail sales still hold the vast majority of PC game units.

In a new chat at Gamasutra, Runic Games' CEO Max Schaefer stated that sales of its fantasy action-RPG Torchlight are now "well over" 600,000 units. However sales for the downloadable version of the game have topped the boxed copies by a ratio of almost four to one. Those numbers might be affected by the fact that Torchlight started as a downloadable game first, in October 2009, with a retail release coming a few months later in January 2010. Sales of Torchlight have trailed off by 10 percent every week, according to Schaefer but adds, "It still sells like crazy every time it goes on sale." The developer just announced plans for a sequel, Torchlight II, that is scheduled for a downloadable release in spring of 2011.
