Not impressed with the linked article. There is prejudice about video gaming among people who don't game. For example, the average American watches about 21 hours of TV per week, and no one says this is a crisis. But if it's 21 hours of video games, it's an "addiction." This in spite of the fact that there can be both social and interactive aspects of video games, while watching TV is not social and is non-interactive. There is more social contact, and more brain stimulation, in gaming than there is with television, but no one bothers about television anymore because it's an accepted national pass time that goes back 70 years.
There's never much science behind these observations. The article reads as a series of quotes from "experts" with very little research mentioned. There's a reason why video game addiction isn't in the DSMIV and hasn't been officially designated as a disorder - because it's junk science.
