The problem is the Roblox games have exclusive timed events that give the children FOMO. So much that they have breakdowns and refuse to do their normally scheduled activities. And it changes their behavior.
Broadcast TV (UHF/VHF) was exclusive timed events which gave everyone FOMO, at least until the VCR became commonplace and affordable.
That gave you the ability to time-shift, as long as you could figure out how to set your VCR clock.
