Been playing a lot of Fallout 76 lately and I think that one tweet that said "If the 'Long Dick Johnson' line had been said in a Bethesda game there'd be an entire dlc exploring the lore about him" is probably the most scathingly correct thing ever said about Bethesda's treatment of the Fallout universe. I don't know which Bethesda writer needs to hear this, but it's just a fucking soda brand. Like a regular ass soda.
Ideally the fun of setting a game in a wacky alt future post apocalypse should be that the possibilities are endless for what direction to take the worldbuilding, including, ideally, moving on from the culture of the pre-apocalypse. Or in a meta sense, moving on from endlessly bringing back the same handful of factions and themes in some effort to build 'lore'. 76 came in and broke the only shard of established lore I think needed to be preserved for thematic reasons right from its core conceit ("profiting off war by escalating conflict will bring about the end of the world" is literally the series thesis statement), but I'd forgive it that if it did something interesting with it (It did not.)
76 doesn't piss me off quite as much as 4 does because there are plenty of moments where it makes an effort to do its own thing free of the shackles of being 'a mainline Fallout game' like all the fun stuff with the cryptids and mutant wildlife and survivalist themes; and even the initially criticized haunting emptiness of finding only audiologs of long dead survivors is poignant....and then you go into a town and there's more fucking Nuka Cola and Brotherhood of Steel. So close.
