It’s entirely possible for kids to happily swim, walk, bike, play board games, surf, scoot, love searching through rockpools at the beach, play with their pets, read books, make art and crafts, go to Scouts or Guides or do any other of the huge range of activities out there, and also enjoy computer/video games without getting addicted.
My son played Fortnite for a while, then he lost interest and has gone back to Minecraft mostly these days. He does not find anything that doesn’t have flashing lights and gore “flat and dull”. Just last night we were going to Scouts and he commented how cool it was to see the new moon cradling the old, and we stood and talked about different stars and planets for a while in the dark. He is a thoughtful and balanced kid who enjoys a range of activities.
My brother and I grew up with some of the earliest computer/video games, some of which involved shooting, jousting, sword fights, and even destroying villages. We are both intelligent contributing members of society and have a strong anti-gun stance in real life.
Catastrophising about computer games and making dire predictions about their negative effects on kids has been going on for four decades. You are just making yourself look silly and paranoid by getting on your high horse and acting like they’re the doorway to delinquency.
