World Health Organization (WHO) has classified video game addiction as a mental health disorder.
In order to fight this addiction, in my opinion, is to look at the aspect those games that are the most addictive and try stimulating the part of the brain that are addicted.
I'm not addicted like I used to be but I really let it take control as a teen. I played a Massive Multi-player Online Role-playing Game called Runescape (I still play to this day) but it just had to much to offer I felt when I was younger. I was socially awkward and very isolated anyways. It did enrage me a lot though. When player killing and you die and lose all the good equipment you worked hard to obtain. Well that's enough to strike a nerve in me. Now adays I'm a lot better with it though. I play once in awhile and I don't get mad anymore.
I believe the best way to get rid of videogame addiction is just going cold turkey and not playing anything for three days. Sure, it might suck the first three days, but once you get over those three days then the pull of video games can lessen, and you are free to do other things.
