"In August 2010, Wired reported that a man in Hawaii, Craig Smallwood, sued the gaming company NCSoft for negligence and for not specifying that their game, Lineage II, was so addictive. He alleged he would not have begun playing if he was aware he would become addicted. Smallwood says he has played Lineage for 20,000 hours between 2004 and 2009.In 2013, a man from China observed his sons addiction to video games, and decided to take action. He hired online assassins to kill his sons virtual avatar every time he logged in. He hoped that being relentlessly killed would help his son lose interest in this destructive habit. Inclusion in the ICD-11
In the draft versions leading to the final ICD-11 document, gaming disorder was included alongside gambling disorder under "Disorders Due to Addictive Behaviors". The addition defines as "a pattern of persistent or recurrent gaming behaviour (digital gaming or video-gaming)", defined by three criteria: the lack of control over playing video games, priority given to video games over other interests, and the inability to stop playing video games even after being affected by negative consequences. For gaming disorder to be diagnosed, the behavior pattern must be of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning and would normally have been evident for at least 12 months.
Video game addiction (VGA), also known as  gaming disorder or internet gaming disorder, is generally defined as the problematic, compulsive use of video games that results in significant impairment to an individuals ability to function in various life domains over a prolonged period of time. This and associated concepts have been the subject of considerable research, debate, and discussion among experts in several disciplines and has generated controversy within the medical, scientific, and gaming communities. Such disorders can be diagnosed when an individual engages in gaming activities at the cost of fulfilling daily responsibilities or pursuing other interests without regard for the negative consequences. As defined by the ICD-11, the main criterion for this disorder is a lack of self control over gaming.The World Health Organization included gaming disorder in the 11th revision of its International Classification of Diseases (ICD). The American Psychiatric Association (APA), while stating there is insufficient evidence for the inclusion of Internet gaming disorder in the Diagnostic and Statistical Manual of Mental Disorders in 2013, considered it worthy of further study.Controversy around the diagnosis includes whether the disorder is a separate clinical entity or a manifestation of underlying psychiatric disorders. Research has approached the question from a variety of viewpoints, with no universally standardized or agreed definitions, leading to difficulties in developing evidence-based recommendations.
