It's one of those classic eastern European based ones, in that it is very obscure and almost framed as a complete antithesis to the rest of the game play that is encouraged for the rest of the game.
After all this Fallout 76 stuff I went back and started playing New Vegas again.
Best way I can describe it is that Bethesda are like someone trying to explain a complex mathematical concept that they've only learned by rote, against someone who understands the base concept. It feels like everything Bethesda have done with the Fallout IP is tick two boxes "Post apocalyptic, 1950's schtick" and then moved on.
It's not something that's obvious until you see it done properly, and then you can't help but note it's absence.
Bethesda do the large world exploration stuff reasonably well, but their "RPG" choices just aren't choices and their stories suck. It's a collect/kill quest every time, and they don't factor in what would happen if the player decides to do something else. So you choices of "yes I'll help" and "no I wont" boil down to "Yes I'll help you right now" and "i'll help you later after being a dick to you now". Admittedly, the Bethesda titles are kind of at their best when they're not trying to force a story, when they just have their "exploring" adventure stuff that you stumble upon and aren't following a shitty compass marker to drive your experience.
Their characters and situations aren't even close to the likes of "The Master" at the end of the first game. They don't seem to understand the Brotherhood of Steel, they just shoe horn them in because it wouldn't be Fallout without them. Even the Super Mutant's are just an underappreciated bullet sponges added to the game without any of the complexity and interest that the non-Bethesda titles have.
Rant over, New Vegas is still amazing.
