Gaming is now a part of growing up for many kids and why not? The key is balance. My two (7 & 8) have a PS4, iPads, a wii and access to a Mac. They use these a fair bit, but between them they also race BMX, play rugby, football and hockey, love Egyptology and other ancient periods (they love the British museum) , cooking, dressing up, hanging with their mates etc blah blah blah.
My opinion is that ‘banning’ gaming is counter productive. Your approach to parenting overall is what counts. Helping them develop a mature and intelligent approach to games which includes monitoring any online presence and building their resilience to being manipulated is no different to the mentoring you most likely already provide for their face to face friends and social situations. Computers, games, VR etc aren’t going away and they aren’t the problem. I’m unsure why, in the technological age that we live in, you would want to deprive your children of those experiences and developing those skills.
