In a recent interview with IGN, Howard confirmed that all previous Fallout games, including New Vegas, are part of the same canon within which the Amazon series also exists.
“There might be a little bit of confusion at some places, but everything that happened in the previous games, including New Vegas, happened.
The ongoing Fallout fever kickstarted by the success of the Amazon series has also brought with it renewed widespread interest in the Fallout games.
Series veterans were quick to point out that that was inconsistent with the larger timeline, since in Fallout: New Vegas, which is set in the year 2281, Shady Sands is still very much standing and functional as a hub of civilization.
