Sounds like you are confusing solo with single player.
No, you are. This is a multi-player experience where players are tasked to make this world interesting to each other. You make it sounds like if it was some SP game with fun quests, lots of exploration and when you are done, well, you have finished the game. There is no such thing, quests are poor, there is no NPC and there is nothing to achieve as a goal for any single player here.
This is a MMO light, like Conan, it is a persistent world where you are supposed to gather resources with friends, build a base, trade with other bases, attack them if you want to and so on and so on.
That is what the game is about. People are supposed to play it for months.
And it is piss poor at that.
Bethesda being Bethesda they tried the theme park approach, they just dropped the charade about this is a destroyed world and you have to survive it.
Everything you knew has been destroyed? No problem, you do not care, gather some friends, and build a base. You are one cold bastard.
In truth, you have nothing really to survive to since other survivors cannot really kill you if you do not want to, food and water are never really an issue and radiations are a mere inconvenience.
What about the other survivors who were not in any Vault? Did they become cannibals, raiders, slavers or whatever they had to do to survive? No, just no, only voices on some tapes because bloody tapes are the kind of technology to survive a nuclear after effect.
Come on, enjoy it if you want but do not present as what it never was meant to be.
