Exactly. You can watch TV whilst you eat lunch or dinner. Gaming has to be a sole focus activity if you want to experience a game like TLOU. 

If you're playing a single player story driven game like TLOU and trying to watch a sitcom in the background, you're doing it wrong.

I was explaining to my coworker how I have 3 categories of game:  

Braindead/easy. Requires little to no thinking. You can die but it's meaningless. Perfect to watch a show at same time. Astroneer, No Man's Sky, GTA V, Kirby.   

Brainpower. Requires little brain power. Can watch video but pause required for harder part/planing. Vampure Survivor, Risk of Rain 2, Deep Rock Galactic.  

PHD. Required so much knowledge/brain power that you need to focus or you will lose reputation and actual good stuff. WoW, hardcore game like RotMG or PHD level like KSP or Path of Exile.  

There's a mood for gaming.
