So I've been planning and getting prepared for the long fun task bringing FO1 to the FO3 world. (Also later on FO2) I'll be using all the story, quests, etc etc of the old one. And at first I was set back by the overland areas covered in one and two being about 500 sq miles each. FO3 is about 20 sq miles. So I was toying with the idea of still having the "overmap Indiana Jones style" traveling or scaling the wasteland down some. When I remembered my google earth... so I placed both maps on the world as overlays!
FO2s map was very accurate, but FO1s was slightly more artistic. I ran across another problem... in FO1 Vault13, 15, and Shady Sands all fell in Nevada not Cali. lol So this actually causes V13,15, military base, and ShadySands/NCR to be located in two different places! New California Republic (NCR) indeed! ...more like New Nevada Republic (NNR).
Oh good bit of trivia(and tip for my future mods)... V15 from FO1 nearly matches right with Area 51.
Also New Reno doesn't match Reno either. It matches the S side of Lake Tahoe w/ Sierra Base matching the N side.
