Child is addicted to video games

A little background, because I think it's kind of relevant. I recently acquired full physical and legal of my ten year old son. Before, he was coming up to visit me during the summer from a different state.During the summers that he came up, we would play games but we did other things, like biking, going out and walking places, swimming, just doing non-screen activities.Well, over the years that he was not with me he began to gain more weight and become more sedentary, which is the problem now.Gaming is his life. His dream is to become a famous Youtuber(Markiplier and JackSepticEye are his heroes, even though I think they're killing his brain cells), making video game content and he actively works towards that dream by recording videos on his inexpensive smart phone. I would never want to take that dream away from him.But he treats his games like a drug. He's unhappy if he doesn't have them. All he thinks about is the next time he can play. If I'm having a conversation with him and the conversation begins to trail off, he'll always tell me something that is from a game or youtube video that he watched. I can tell it's always on his mind. He has no other hobbies or interests.His exercise and motivation have plumetted. He is considered to be overweight, bordering on childhood obesity.Other people I have asked have recommended taking them away from him altogether. I agree, he should go through a 'rebhab' period where he finds other things to enrich his life.But, here's the problems...He has no other hobbies/interests. When he is punished for bad behavior and games are taken away from him, all he does is sit and sleep.He's made several friends online. All these friends that are his age all play on Xbox Live. I hear them talking all the time while playing different games.He doesn't have any friends that he hangs out with in real life. He transferred to a local school mid-semester on the last year of lower-elementary. All friend groups and cliques have been established and most of these kids have been together since kindergarten. For 5th grade, all the kids from his school and 3 other schools in our district will be going to a different school in our district. I think/hope it will be easier for him to find and out-of-school friend.Does anyone have any advice? I'm a single dad and I've never really had to be an enforcer of rules, since I only ever saw him in the summers and he was very active at the time. via /r/Parenting http://ift.tt/2nRhY7H
