That kid is now known as the kid who got Roblox banned among their group of friends, not a nice thing to known for. This will be seen as a punishment by them regardless of how you frame it especially once the other kids at their school become aware of it.
Ouch. Good luck navigating this one as your kids get older.
Some of these games, like Starfield, cost an absolute fortune ($120 AUD where I live on Steam). I’m simply not going to pay that much for a game but will happily pick up something like Sea of Stars for less than half the price.
