There's a certain culture that prefers "efficiency", punishes non-productivity, and every little slack, even enjoyment of life must be "earned". In that culture these video games that are pure playfulness (but it doesn't just have to be video games, it could be poetry, whatever, just something with no productivity!) are the antidote.
I'm happy I wasn't born into this culture. (I've seen and heard absurd, almost comical examples of this from my colleagues, like justifying not replacing a black and white TV in the 1990s... From my point of view they're ascetics, but from their point of view they're normal.)
