Fallout 1, 2 and NV took place in relatively arid areas. Those are the only games I'd consider mostly canon.
Ugh... You do know what the definition of "canon" is, right?
From Wikipedia; "In fiction, canon is the material accepted as officially part of the story in an individual universe of that story." I don't care what your opinion is on BethSoft or their games, but Fallout 3 is, without a doubt, canon. In your fanon, it may not be, but that's not what canon is.
As much as I'd like to see F3 stricken from the record, it's here to stay. You have to include it into canon because you don't get to decide what is and isn't canon. Whoever owns the IP gets to decide and, despite how shitty it is, Bethesda is the owner.
"Bethesda decides what's canon." Every time I say that, a little bit of me dies inside.
