I tried to do the same thing with an expensive bottle of liquor a few weeks ago. It only worked for a week :/
If alcoholism, luckily it is taken "more seriously" than video game addiction. Although now as I get older I just realize addiction is a trait we all have the propensity for, and some people just manifest it in healthy ways where as some of us in not so healthy ways. I have people in my family that were compulsive gamblers, alcoholics, workaholics, and drug addicts, sometimes a combination of all four -- all different forms of addictions. Sometimes I view my video game addiction in that light: "well at least it wasn't drugs or alcohol" but, who knows, maybe in 50 years we will find out that it harmed me just as much.
