This is Fallout.
I always felt that in many ways Fallout 3 was more of a sequel to Fallout Brotherhood of Steel as it shares a lot of the same elements. How the BOS is portrayed, bandits, ghouls (in FOBOS we started to run into more zombie like Ghouls such as the glowing ones), and the Super Mutants, and many more things.
Pretty sure that if the Enclave had been in this that they and the Fallout 3 ones would feel very similar too.
Bethesda may not claim that it is canon but it would work better as the prequel to Fallout 3 than FO1 and FO2.
