Gaming doesn't work in hour long stretches. Plus you might **only** have that hour or two of free time so it's either watch a show **or** play a game, not both. 

Watching a show is easy and there's no learning curve that usually takes longer than an hour. 

If you only played The Last of Us for an hour you wouldn't even have learned all the mechanics yet. 

And if you only have an hour then you're not going to progress in a natural way. 

And with some save systems it's not even possible or that efficient to stop in the middle of something if your hour is up.

Also if you are not playing frequently, half the time you are spending a chunk of that time installing updates.
