In the first six months of 2010, 11.2 million full games for the PC were bought online compared to 8.2 million physical unit sales, said NPD Group. Topping the list of download sites was Steam, the online shop of game developer Valve which created Half-Life, Left 4 Dead and many others. Despite the prevalence of downloads, physical sales generated more cash.
NPD said that PC sales in shops made up 57% of all cash spent on PC games compared to 43% for downloads. NPD said this was due to the higher average price of games sold in stores. The figures also revealed that the total sales of downloads and in-shop sales were down 21% on the same period in 2009.
