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.

That sounds like me when my parents made me go to bed instead of watching "The A-Team" or "Knight Rider".

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.

Any social games have this. I wasn’t an Everquest or WoW player, but I knew some, and scheduled raids with friends were a common thing. Minecraft servers hold events, etc.
