Excessive video gaming could become an official disorder

[Evil Yoshi Toes]

As Zero Kirby said, addictions are considered a disorder. That point is made very clear in rehab programs. In order for it to be an actual addiction disorder the person must be unable to stop himself and must need the help of others to overcome it, so if he can stop himself but just doesn't feel like doing so it isn't an addiction, he's just lazy.
