The thing that sets video games (and social media) apart from these other things that you mention is that they are far more updatable, and not surprisingly this attribute is taken advantage of for good and for ill. The ill of course being that they are able to be updated in such a way that they hack your attention / biology ever more efficiently over time. This doesn't happen with chess, reading, or running. At least, not without these activities becoming intermediated by updatable technology. Which IS happening, but still, not as much.
