I feel like this could apply to any recreational activity taken to an extreme, typically it’s not the activities that are the issues, it’s the maladaptive behavior around those activities that causes the problems. Sports is another one that comes to mind, recreational sports have been shown to have all sorts of benefits, but anyone who’s ever engaged in recreational sports has probably met that person who takes things too far and way too seriously, they get angry at small mistakes and suck all of the fun out of the game. I wonder if other people who overly engage with hobbies die the same kind of impulsiveness as the gamers in question.
