The New Yorker likened its popularity among teens to Beatlemania and the viral Tide Pod challenge.
Randy Kulman, a child psychologist in Rhode Island, told Live Science that 'Fortnite' addiction is a "phenomenon" that has taken over his practice.
He said many of his patients become obsessed with the game and admit to playing it thousands of times, often hiding from their parents.
Dr. Leonard Sax, the author of "The Collapse of Parenting" and "Boys Adrift," said that a healthy gaming diet for children shouldn't be longer than 40 minutes a night on school nights, and no more than an hour on weekends.
“That adds up to six hours a week. If you spend six hours or less playing games, research suggests it doesn't impact school performance or real-world relationships,” Sax said. “But if you spend more, and there are many who play 20 hours a week, then you're more likely to see an impact.”
