Each of the zones comes with an element which had the power to be a part of a bigger quest so as to have the gangs overthrown. There is a robot army in Galactic Zone which could have been reprogrammed. There is an army of ghouls in Kiddie Land, which is led by a wizard, which further hates Raiders.
The last holdout of the Raiders was supposed to be Dry Rock Gulch. People like Cito and his group of Ghoulrillas have every right to fit in. A reprogramming of the World of Refreshment could have provided psychotic Mirelurks or something similar.
In the end, all of these things would have added to an incredible DLC. In fact, in the beginning, it did feel like that. As the player, you notice a bunch of gangs being held together by a single boss, and there is the promise of wealth included in a place of leisure.
The DLC initiates a conflict raised among gangs, but no one manages to deliver. The DLC is a fail for those people who don’t wish to murder each other for a living. As a final DLC, gamers expected something more robust than what was offered by Nuka World.
