Anything can become an addiction to anyone; it’s the overall impact that that addiction has over all that is more so taken seriously.

Your site says that 10-15% of all gamers can be considered an addict. So if roughly 69 % of the world plays video games, and there are 6.7 billion people on the world, which means if we took the high road: 1 billion people are addicted to gaming? It seems a bit high considering the amount of people addicted to other things.

Gambling addiction is very closely related to Gaming since they are basically games, yet only roughly 15 million people are considered addicts of Gambling? So the 1 billion gaming addicts seems unbalanced…

About 13 million people in the word are considered Alcoholics, but they also go out driving and get people killed by drunk driving.

If each alcoholic affects the lives of four or five others " spouse, children, employer, employee, innocent victim of accident, or other " then our 12.1 million alcoholics have an impact on 40 to 50 million others for a total of about 60 million citizens. The president of a state association of judges stated that "90 to 95 percent of all the cases that come before my bench " civil, criminal and family " involve alcohol." Alcohol may not be the sole cause, but is a part-cause in much juvenile delinquency, illegitimate pregnancy, truancy, and fights. Numerous reports indicate that about 73 percent of felonies are alcohol-related. A survey of the literature shows that in about 67 percent of child-beating cases, 41 percent of forcible rape cases, 80 percent of wife-battering, 72 percent of stabbings, and 83 percent of homicides, either the attacker or the victim or both had been drinking. Automobile crashes in the United States kill nearly as many people each year as the total of 46,483 American soldiers killed in the entire dozen years of the Vietnam War.
Seems to have a bigger impact seeing all of the death involved…

What about the 1.4 Billion people in the world who are smokers?

Around 6 million people may die each year worldwide staring in 2010 because of smoking and tobacco related disease, according to the World Health Organization – including over 438,000 Americans, 650,000 Europeans and 1.2 million people in China.
Tobacco use will kill 1 billion people worldwide in the 21st century if current smoking trends continue.
One billion men and about 250 million women use tobacco every day around the world.
What about the drug users? If you want to see scary numbers go look at this site, it was way too much depressing figures to quote here:

So yes Video Gaming can be an addiction and while there have been some violent acts tied to games, and yes it’s a shame that people let games control their lives in such a way... until I see more solid statistics like the above involved with video game usage I have more important things to worry about.

On the flip side this could help someone also but in the end you can't really be mad at people’s reactions to such a post because also remember the number one response of an addict is denial.

Over all yeah the site was an interesting read, but not one of my top concerns in the world.
