It depends on the story.
I can see why you wouldn't want something too civilized in something like Fallout, though, to keep the setting apocalyptic.
What I like seeing is that the humans adapt and create new groups and social structures, even if it's hopeless or not 'civilization'. Because that's what happens.
For example, I read a book 'Jälkeen vedenpaisumuksen ' (I have no idea of the English name.) that told about the world after a nuclear war. Humans were doomed, no children were born, everything was toxic, etc.
But humans still survived and struggled, and formed clans and fell in love, hunted and traded.
And that made the book work. It might have been about humans going extinct, but it was about how people acted in a situation like that.

The likely real-world apocalypse is the ecological one, which may claim all of humanity despite it's tendency to not wish to die off.
Even still, it's pretty unlikely all of humanity dies off. Unless the planet itself is destroyed while we're still on it.

Quite frankly, a game or setting where there is no hope and the world is just utterly and hopelessly irredeemable and broken sounds boring. It's kind of why I'm not too into "cosmic horror" Call of Cthulhu style roleplaying games where everything is hopeless in the face of bone-shattering power and mad-God terror. It's just all too... blah. I don't know, for me the fun is in the story and the story is in the human experience of being able to beat the odds, in hope.
Call of Cthulhu really isn't about the apocalypse, it's about the threat of one. There really isn't much interesting stuff that happens after, or even during the apocalypse, when the Great Old Ones have come back, but humanity can delay it, at least.
Of course, Call of Cthulhu still isn't a setting that's optimistic. You can't really defeat them, but you can survive, for a while anyway.
