Exactly. Something of a challenge, even though post-apocalyptic survival is enough of that to begin with. Something for hardcore motherfuckers, even though there'd be little to nothing of real value to loot. Something for the sake of iron-balls exploration or just getting rid of raider pests rather than finding treasure troves.
That's great sentimentality until some biker guy breaks your legs with an iron pipe.
I'd rather just survive and maintain a relatively normal existence. That's challenging enough when the world's gone to hell.
