He didn't think you'd actually make it to him, but hey, if you're there.perfect successor, ready for grooming. I bet he only released you when he learned of his imminent demise. But he is all about being emotional when it's convenient to him, calling you father, trying to get you on his side before he dies. Seriously, you trust your son (if it's even him, I still have my doubts)? He obviously feels no emotional connection to you. Though if there does have to be a canon ending it's most likely either the Minutemen or the BoS. Nuka-Town is the center of trade and government, Kiddie Kingdom becomes similar to the Strip in that it's casinos and brothels, Dry Rock Gulch becomes a large military fort, The Galactic Zone is turned into a massive research institute, the Nuka-Cola Bottling Plant and Safari Adventure turns into factories and plants with everything in between the parks turning into a giant residential district. The park is split into separate districts. It's military might protected it's large brahmin trains to the point no raiders would go up against them. A small city-state in terms of land but due to the size of it's population no one picks a fight with it. Nuka-City would become the jewel of the east coast. The City itself would be a center of trade and industry due to the re-production of Nuka-Cola and the construction of foundries. Nuka-City would turn from a collection of parks into a unified city with the countryside being turned into farming communities. Nah, should go with just a war happening in the Commonwealth but the Commonwealth ends up in the hands of the Nuka-World raiders with Nuka-World eventually turning into a giant city and taking the name 'Nuka-City'
