"Addiction ~ noun.
The state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming, as narcotics, to such an extent that its cessation causes severe trauma.
Now I am not the first person to suggest that video games may be addictive, in fact a simple google (or any other good search engine) search will give you hundreds of articles and studies into this very subject. In fact there have been so many in recent years that when the next version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) is published in 2012 video game addiction may well be an actual clinical disease.
So what? I hear you ask. Read on to find out."
