Gaming will make you violent. Gaming gives you an outlet for anger. It will calm you. It may shrink your attention span. Just 20 minutes will bolster your eyesight and improve your reflexes. However, playing for hours will restructure your brain in ways we don’t totally understand. It can be a worrying sign of depression, but also make you happier.

These are all the kinds of claims we’ve seen from research into the psychological and physiological effects of gaming since it was ‘TV games’. Or maybe even before that, when gaming meant playing Pong at an arcade.
