Based on a significant increase in correspondence to the author from parents, teachers and psychologists concerning "addiction" to online video games like "World of Warcraft", this paper provides a brief overview of the main issues surrounding excessive video game playing among adolescents. As an aid to educational psychologists, and based on two decades of the author's own research in this area, this paper briefly overviews: (i) online gaming addictions, (ii) the differences between online and offline video gaming, and (iii) video gaming benefits. The paper ends with some practical advice that educational psychologists can give to parents about the safe playing of video games.
