This is true and a fair point. You might say that even video games have been around long enough that we can start to name the "classics" (though we might judge more about the game than the music -- maybe this is like how some classical music we perform alone now, originated from opera etc.) On the other hand, the article does mention newer games like Halo and Mass Effect. So it would be more sensible to complain about hearing Mass Effect when you wanted Mozart.
