Hey, it looks that we’ve had a same idea.
Well, I was playing “The Dicaprio Cataclysm”, before it become “The Dicaprio Cataclysm” 
For me it was called “Long Dark Cataclysm” (no zeds, only wildlife, 1 city size and la-a-a-arge distances between them, very low item spawn)
Playing a “Walking Dead Cata” for a while with setting almost similar to yours.
I was trying to play a “Mad Max Cataclysm” (like yours, but without ‘weapon pack’. Also used it on experimentals that have a ‘desert’ world type.)
