Nuka Wold quests. Suggest. (Fallout 4)

Foul4 license + season pass. And finally, the last DLS. Well, I think we'll see.
To be honest, it bombed me a lot. It turns out that you find yourself in a nuke and you have the opportunity to become a raider boss, while cleaning the territory of the entire park = the next step is a commonwealth, where you (I'm talking about my version of the game) built settlements and all that, and then decided to give everything to the raiders? WTF? At the same time, receiving the same tasks from the leaders of the gangs that from the minits?
If you refuse to do this, you have to kill everyone and ... everything? The next step is the power plant fix. and how is the game over?
Is this all DLS?
The people who played the pirate, share the info .. is everything so dull? or is there still hope for something more interesting?
I exclude the quest to fix a large computer (I haven't finished it yet, I haven't found all the cores) and the quest to find crap with glasses.
