It’s worth noting that these are retail figures only, meaning that the biggest share of PC game purchases (those made online) are not recorded. With that in mind we shouldn’t be too surprised to see that just $538 million were generated by the retail stores last year in the US (an impressive 23 percent drop from 2008). But in a world where you can order a coffee online and have it delivered at home, these numbers shouldn’t be too strange!
