"We welcome any and all research about video game consumers and this one certainly seems to have a lot of merit. A concerning aspect of the research for me is that it might lead one to draw the hypothesis that game addiction is a mental, rather than behavioral, process," Halpin said. "That men are more drawn to violence than women has generally been stipulated for some time, and that male gamers prefer fighting and shooting games follows suit. I suppose that it would be more interesting to see how far the correlation could be drawn into other types of media and in other mediums. ... To do otherwise and focus solely on aggressive or violent games, to my mind, seems a play at the sensationalistic and not as helpful as could be otherwise."
Reiss admits, however, that, at least when it comes to playing video games, biology isn't destiny.
"Just like all behaviors, this is genetic as well as environmental," he said. "All behaviors have both nature and nurture components to them."
