Regulations target mobile game In what case would Tang Dynasty poet Li Bai and Western hero King Arthur meet and fight against each other? If not in your dreams, then perhaps in a MOBA (multiplayer online battle arena, 多人在线竞技游戏 ) game called King of Glory ( 王者荣耀 ). Created by Chinese company Tencent, King of Glory was one of the most popular MOBA games in China in 2017. It has over 60 characters to unlock and play as you progress, each with their own unique style and abilities. The characters cover different times and countries. Some are real historical figures, like Li Bai.Some are not. Players use them to battle against each other or team up to fight. The winners can reach higher ranks. However, along with its popularity, problems and criticism have also come. Not all reviews of the game are good. Some think King of Glory can confuse children by using incorrect historical references ( 参照 ).For example, the poet Li Bai is described as a killer; Jing Ke, the man who tried to kill the first emperor of China, is a girl in the game.But more people worry about children playing the game too much and spending too much money on it. Players below the age of 19account for 25.7 percent of the game’s players, according to Chinese analytics company Jiguang. An incident in which a 17-year-old boy had a stroke ( 中风 ) after playing the game for 40 hours has alsocreated controversy ( 争议 ). Following this criticism, Tencent added a timelimit feature to the game to prevent kids from playing too much. As of July 4,2017, children under 12 years old can play the game for only one hour a day,while users between 12 to 18 get two hours. Those who try to play beyond the time limit will be locked out of the game.
