@AbandonedAmerica Why is it that some places disappear completely and others somehow linger on as ruins? If there's a "specialness index", I think it influences that. Failed places that weren't special just get built over. No one notices; no one cares. It's the weird stuff that lives on in decay. It's harder to erase. It's life force still has influence.
I don't know how to put that into words any more effectively, but you probably understand what I'm trying to say.
