Getting some story ideas from this discussion, but not stories I really want to write.
There is plenty of scope to write PA stories how you like.
They don't have to be about loss, the degrading of civilised values, and the resurgence of a world where the best armed is king, or every moment is a violent battle against zombies.
You could write about how compassion and kindness can be amongst the survivors.
You could write about how people find love or purpose which life in the mad rush of the twenty-first century didn't offer them.
PA is an interesting setting, but the story could be horror, romance, cosy, thriller - whatever you want to make it.
