I wouldn’t want Fallout 4’s incongruous fps shooting or the terrible “perk” system tainting FNV, tbh. Frankly I’d be pleased with the arrangement that Bethesda never touches FNV or anything related to it again, but blue sky thinking’s just that.

It continues to worsen the longer you try and consider the motivation for the 11 year old. Of which I can think of at least 2, if not more, but I’ll spare us all.

My love for the first two games is sortof why I’m avoiding it. I mean, I even didn’t like the concept of the proposed Black Hound game being called Baldur’s Gate 3. So I’m going to come in with opinions and just ruin it for myself even if its as good as some say, and that’s assuming WoTC having decades to ruin every scrap of coherency in the setting’s lore hasn’t impacted things negatively. (One thing I really appreciate about Larian’s handling of BG3 is that they gave me enough info to come to that conclusion first.)

I mean the first two parts are definitely true.But then we stayed for 10+ years attempting to rebuild some form of stability, decided to finally pull out after more than a decade, and what was built broke down disappointingly in the face of the first threat. Tmu, the reasons for that are varied, although some of its definitely on us. We approached the entire region’s politics wrong apparently and with a very modern western mindset of a country held together with an idea of some unified identity that doesn’t seem to really hold true for the region (or any region at first probably). I believe station/position abandonment in the fracturing nation was problematically common as people rushed back to their homes/families, or just to generally flee, instead of actually being a larger regional barricade against the threat, as an example.
IIRC, there was a similar problem with even the First Continental Army and Congress early on actually. With regional interests often superseding national goals in the minds of individuals and representatives.

So far as power vacuums go, as I alluded to, they had an elected government (there’s probably some debate on the accuracy of those elections while being occupied by a foreign government of course) and a standing military that was actively deployed. A not insignificant number of them tried to hold out, to not undercut their efforts, but its also true it wasn’t a truly unified defense in the end. Whether or not they would have been a more effective void-filler if we’d stayed longer or left sooner are just huge what-ifs.
