Perhaps Chris can find an alternative method that also makes his time productive. For instance instead of a video game maybe a physical game that way you get your exercise in as well. Chris' example is a classic example of how someone sees that they have a problem but at the same time aren't direct about what actions they will take to correct it. In other words they are satisfied with their state. This isn't to say that Chris' video game addiction is seriously affecting him but that even he has noticed that its not productive in his life.
My gaming consumption is like my alcohol consumption. I don't do it all the time (Maybe 1/2months), but when I do, I binge. I will find one cool game that has been out for a while and finally buy it (Or around the holidays and get it for a present), but then I'll play it for an entire weekend to the exclusion to almost anything else. I am happily married and my wife is fine with this. She helps me make sure I take care of myself whenever I do binge play video games, but likes to see that I have interest in something. Most of the time I am working or interacting with my family, but once every couple of months I need me time.
I also don't agree with your (JB) assessment of how to qualify as addicted to video games. I would add the caveat that if you meet any of your qualifications to the point that they actually disrupt your life. I ignore almost everything while I am playing, but I don't play often enough for it to actually disrupt my life. I get upset when I lose while I'm playing to the point that my mood changes for the worse significantly, but not to the point that I am abusive (To myself or others). And I may talk about the cool game I am playing quite frequently, but not to the exclusion of letting others talk or in taking interest in what they have to say.
The best way to overcome one addiction is to become addicted to something else healthier. The thing about games is it has no other value other than entertainment so as an addiction you won't get anything else done. At least if you're into sports your body gets exercise.
Video game playing negatively influences adequate sleep and bedtimes
A new study found that gamers will push off obtaining adequate sleep in order to continue video gaming. Results show that on average, gamers delayed going to bed 36 percent of the nights they played video games. Average game playing was 4.6 nights per week. The average delay in bedtime on the nights spent gaming was 101 minutes. Ref. Source 4e.
Man admits to spending $1M on video game
A Northern California man pleaded guilty in federal court last week to wire fraud and money laundering, admitting he stolen nearly $5 million from his job as a heavy-equipment operator and spent about $1 million of it on a video game. Ref. Source 1z.
I'm addicted to gaming, but it's the least expensive addiction I've seen so I'm alright with it. I don't allow it to interrupt my time with my wife and daughters, but I certainly do miss out on some sleep most nights!
I've been addicted to gaming since I was young. I think it's because I have an active imagination. That said, I don't see it as a bad thing. Sure, I'm a bit of a geek, but I'm a bit not. Just like everyone else, I'm complicated and this gaming addiction is part of me.
