Hey, don't blame the researchers. Blame the sensationalizing media, politicians, and other people who distort science for their own nefarious purposes.
This article should have been more subtle. It kind of overshot the mark for me. I get what you're trying to say, but the portrayals are too exaggerated.
I have issues with #5 and 3. I doubt a high percentage of the games out there use #5. And what is so wrong with number 3? I doubt there are a lot of games that play it straight with the genre delineations. And a game's genre doesn't specify whether it is good or bad anyway. I'd even argue that using just one genre may be lazier.
