But, Gentile pointed out, "A lot of video gaming isn't the same as an addiction. Some kids can play a lot without having an effect on their lives. It's when you see other areas of your child's life suffer that it may be addiction. Parents might notice that a child doesn't have the same friends any more, or that he's just sitting in his room playing video games all the time. Or, there might be a drop in school performance," he said.
