This issue about the game addiction, it has destroyed many life's, many careers, many homes and business. I believe it is a disorder because game addiction always affect the brain, reduce the thinking mentality of that person thereby putting that person memories into danger.
Actually what else can he offered to the game addict than to try to make them to understand about the danger behind it and what it is capable of causing apart from the fun they seen in it.
It is definitely an issue. I don't think being a hardcore gamer is good news for anyone.
