If you've been online at all since the Fallout show aired, you'll have seen a wave of angry New Vegas fans claiming the series contradicts the game and that Todd Howard and Bethesda are working to erase Obsidian's work in some machiavellian conspiracy. With the backlash mounting, Howard himself has come forward to clear the air.
"There might be a little bit of confusion in some places," Howard told IGN. "But everything that happened in the previous games, including New Vegas, happened."
Spoilers for the show follow.
One of the big complaints is that, in Vault 4, you see a whiteboard with a timeline of the NCR's history. It lists the "Fall of Shady Sands" happening in 2277, with a big arrow pointing to a nuclear explosion. For context, Shady Sands is the first capital of the NCR and we know that in New Vegas, which takes place in 2281, it hadn't been nuked yet. However, 2277 is referring to the fall of Shady Sands, not its destruction - according to Howard, that comes "just after" the events of New Vegas.
In Obsidian's game itself, it's shown that the NCR is stretched too thin and reeling after the first Battle of Hoover Dam, hence why the Legion has been able to gain such a foothold in the Mojave Wasteland. So, not even the "Fall of Shady Sands" contradicts the games, as we saw firsthand in New Vegas that the NCR was on the brink of collapse. What state they're in now, we'll have to wait to find out.
The show even ends with a shot of New Vegas, but that has proven just as contentious as the nuking of Shady Sands because it looks to be in complete disrepair.
However, we know the series is set 15 years after the events of New Vegas, and a lot could have happened between whatever ending we chose and now.
It's possible the Tunnelers did invade the Mojave and lay siege to the city, or perhaps it's just falling apart as its new owner struggles to keep the lights on. Either way, its current state doesn't contradict the game either.
