I would be interested in John's take/view on video games violence discussion. Does it translate to real-world behavior change, if yes how, what are characteristics of susceptible people, vs non-susceptible, and so on. General, video game addiction from early age, is that real, or made up concern in John's view... I do not think those topics were covered, although I might have missed it.
