To parents of other heavy gamers...
Please do not attempt to moderate or restrict your son's access to on-line gaming until you have educated yourself about gaming addiction and have prepared, put a plan in place!
We are in the process of trying to wean our 15 year-old off of gaming. He is down to 2 hours a day. Things are getting a bit better, but he is still obviously very addicted. All he thinks about is when can he get back on. Every day is a battle and he is mad a lot of the time. We can't get him to go anywhere with us (not even family get-togethers) unless he will have access to electronics the entire time. He says we can solve that by getting him a laptop or smart phone, Uhh, we're not going down that road.
Two of the resources that have been really helpful for us are 1) A book by Dr. Hilary Cash called "Video Games and Your Kids". She was one of the first to recognize gaming addiction and also has an in-patient treatment center in Washington state. 2) The OLGA website (on-line gaming addiction). Here you can read stories from ex-gamers and other parents and spouses. Very enlightening. If you are concerned about your child's obsessive behavior please check them out. I have dark concerns about the gaming addiction that keep me up at night.
