Maybe I'm weird but I'm glad the Fallout show destroyed NCR and New Vegas.

Now that all of the people who just downvoted without bothering to read this have given me more engagement, let me explain. I will prefice this by saying, I don't like how they did it, however, Fallout NEEDS to move on if the series is ever going to actually survive. Even in the classics, groups that had once been powerful in the first were now laid to the side in the second, the Brotherhood, the Mutants, etc. A big part of Fallout is the cycle of war in humanity, and the fact that the powerful groups always change. Bethesda fucked this up pretty royally in their games considering the brotherhood has been a main faction in literally every Fallout developed directly by Bethesda. Obsidian sort of corrected this in New Vegas with the introduction of House, the Legion, independent Vegas, and the fact that NCR and other old factions have lost much of their power over the years, but even then they still don't let go enough. While the Brotherhood being a major faction, the fact Shady Sands got moved and nuked, and the fact that Vegas (supposedly considering the leaks) got overrun, all piss me off with how they do it, it allows for the series to actually move on from the established groups, and move forward into another apocalypse. After all, Fallout has always been meant to be a POST apocalyptic series. Maybe I'm right, maybe I'm wrong, that's just my take on the matter.

TLDR: Fallout needs to move on, and the show helps with that.
