Interesting take. I'm in my 30s and not sure I've ever known that kind of culture, yet I do understand the sentiment against heavy media consumption (which most video games fall under).

Video games, TV, and movies put me in a situation where I must gamble several hours of my time to digest them. That kind of time investment cannot be isolated from the rest of a day. Media has a tendency to set my mood regardless if I liked it. Most fandoms are radioactive as well. I'm pretty sure what I'm saying is the majority opinion, so it shouldn't be a surprise that so many people shrug their shoulders and strongly avoid both that media and its fans. It doesn't help that there are no shortcuts around this either because if honest critics ever existed they definitely don't now.

The result is that many have a very high bar, and even when it's met they still don't want to sink more than about an hour into it at a time. It's less about efficiency and more about having better things to do.
