When it comes down to it so many people can't cook up anything more than a moderate reframing of the NV set-up.
In our own industrial society the main political disagreements can be boiled down roughly to liberalism vs illiberalism, so its no wonder that any sort of story set in a society that's at least somewhat similar reproduces that. I remember a ZP vid where he dubbed it "fascists vs nutters", and how any sort of nuance you try to add like conflict over resources or whatever isn't very effective because people will recognize the fundamental political orientations of the factions and base their decision on who's good or not on that, above all else. Sort of like how Star Wars with Andor has departed from being a silly good vs evil kids franchise, making the Empire have the same connotations as the Imperium of Man or even Nazis, rather than Mordor which was how I always viewed them: an 'evil' faction, sure, but one that no one would have had a problem with dressing your kid up as for Halloween.
Years of NV glazing have seriously distorted it. It's true that Caesar does talk about Hegelian dialectics, and it's true that high-level questions about "what sort of societies will rise out of the ashes/who will inherit America" are part of the story, but that's only a
part of Fallout's core, not the
entire thing. Fallout should definitely not be a wasteland in stasis inhabited only by raiders and the BOS, but it also shouldn't be a setting where the apocalypse is to its inhabitants as the fall of Byzantium is to us. I don't want to read too much into what is essentially just a fun thought experiment by Warlockcracy, but I worry that people in reaction to Bethesda and the godawful Fallout show's version of the setting will also lose sight of the core of Fallout.
There's a reason why NV was set in frontier Nevada, which is more suited for Bethesda open-world gameplay, and not developed California. In my opinion NV should mark the end of the timeline and the Southwestern United States storyline. Past that point the Fallout universe will only farther from the apocalypse as advanced developed states spread. There's so many other regions that are unexplored, and there needs to be something between between a wasteland stasis where the only conflicts are personal, and a post-post apocalypse where the conflicts will naturally converge on liberals vs authoritarians.
