Hi Jonathan. Interesting, yet please consider the following:

I have an addictive personality, I get addicted to things easily and therefore I am at risk of things that are addictive (and I do know the difference between an addiction and a habit). Because of this, and for whatever underlying reason, I am better qualified to tell when something is addictive and when it's not. I have to take great steps these days to avoid anything that could be addictive and videogames are one of the things that I have to avoid. You may be right in your belief that addiction is a symptom of deeper problems, however, it doesn't change the fact that people, including myself, get addicted.
