The World Health Assembly in 2019 is about to be held this week, and the controversial debate on whether game addiction is a disease will finally be finalized at this conference. In June 2018, the World Health Organization (WHO) promulgated the 11th edition of the International Classification of Diseases (ICD-11), listing "Game Barriers" as one of the diseases. This decision was discussed and resisted by ESA, the Entertainment Software Association, and many game companies. They realized that the wrong decision of this classification would affect the whole world. After the impact of billions of players, the WHO acknowledged that the decision should be based on more rigorous research. According to the description in ICD-11, "game addiction" is a kind of behavior that continuously or repeatedly carries on single-machine or online games. It is characterized by losing control of the game and becoming more and more addicted to the game. As a result, other interests and daily activities need to give way to the game, even after the negative happens.
