You deleted your comment by the time that I was done replying, but I'll paste it here:

&gt; most people assume gaming has to be a much larger time commitment than a TV show, and I'm wondering why that is.

Not *time* commitment, but *attention* commitment definitely. Most people consider watching TV as a passive activity and gaming an active one. They do other stuff while watching TV, like chores, paperwork, research, etc. This is the "adult lack of time" that your friend was talking about.

EDIT. A lot of r/ImTheMainCharacter  syndrome in the replies. You are not representative of all people. Congrats on watching TV with 100% of your brain.

Dunno about you guys but when I watch an intense show like Last of Us or Game of Thrones I have a hard time doing anything else I'm pretty much dialed in.

I can see multitasking when something like Friends is on though.
