His friends will be playing Fortnite, it's an easy game that's hard to win. I play it and have a battle pass, it means doing specific things in game. As an adult that knows how to play I can do these quickly but a young child who won't play tactically may take a while to do them. By doing them you level up and that's what everyone wants as the object of the game is to compete the pass and it unlocks cosmetic items. You do not need the pass to play but young dc will all be showing off at school about the lastest cosmetic item they have unlocked. My squad is led by a guy who was in the military and we play very tactically. We played two days ago and between us took out a quarter of the lobby.
I have gamed for forty years and managed to go to University, have a family and a social life. However I do recognise that game addiction exists. I have friends that are truly addicted and have seen marriages breakdown.
As he is so young you need rules, chores and schoolwork done, make sure he goes out to the park etc. I see many parents complain their dc spend too much time on consoles.
As much as Fortnite and other games have allegedly been built to encourage play and accused of being addictive which I can greet with I also think us as humans have varying degrees of addictive behaviour.
Just like some people cannot say no to the last drink or over eat when they know they shouldn't.
He is still little his personality is still forming only you know your own child.
I let my DS have his own console at ten, we had issues with him once and removed it. His Father took it to work with him and my goodness he absolutely hated us. I have had one friend whose DS had serious game addiction but it was a symptom of extreme anxiety and school avoidance. He remains as a young adult a person with many issues that manifested itself at the time as gaming addiction. He doesn't game at all now but remains very reclusive.
If you let him have it when you want him to get off for dinner etc understand that the length of a match varies though typically it's Fifteen to twenty minutes. He won't ever want to leave mid match, it cannot be paused. Give a warning so he doesn't start a match close to the time he needs to get off. Biggest source of arguments I have had to listen to down the headset.
