China has imposed strict game time limitations for minors partly out of concern they could develop addictions, but a new paper published in Nature Human Behavior found no evidence that the rules have had any impact on excessive gaming at all.
The researchers partnered with Unity to examine more than 7 billion hours of playtime and around 2.4 billion Chinese gamer profiles from mid-August of 2019 to mid-January of 2020, a span of time that includes the imposition of an hour-and-a-half daily playtime limit for minors, or three hours on holidays.
"Heavy" gaming was defined as an individual playing for four or more hours a day, six or more days per week.
