This is a limit per month.
I am not sure one could still function socially playing videogames 80h a month. We are reaching addiction/disease level at that point.
(And how many of us lived in homes where the entertainment was just watching TV every night, I'm sure my dad would watch more than 4 hours of TV every day).
Not to mention people who have nothing better to do on the weekend(or you know, they choose to spend their time this way) and play around 16 hours a weekend - even with not playing during the week at all, that alone gets you to 64 hours a month.
Last time I was on a plane I saw a guy who was ̶w̶a̶t̶c̶h̶i̶n̶g̶ listening to a movie while playing a game on his phone. I was a bit gobsmacked. While I can enjoy one of these activities at a time, I don't see how one can find enjoyment mixing both.
I wouldn't even be a tiny bit surprised if finishing GTA6 via streaming costs you $200-300.
On the other hand I've sunk thousands of hours into sim games and I wouldn't call it reality avoidance.
