For Fallout 4‘s Nuka World DLC, obviously. And as per here:
It’s called ‘Nuka World Glory,’ and it basically throws out all the Raider junk and makes the park clean. I’m guessing that if you want the full effect, narrative-wise, you’ll need to install this mod AFTER you finish the DLC in full Queen of the Girl Scouts mode. It’s not really believable any other way. …Hmm. Each part of the park really should have its own settlement. Alas, I don’t make mods; I just consume them.
