Honestly, I'd have to go with New Orleans for my pick. Imagine what they could do with the whole noir theme, the architecture. The map could even be diversified by having a swampy area that's akin to the Glowing Sea in difficulty, something we could get a taste of in the upcoming Fallout: Miami mod!

If not here, I'd have to say Chicago. It's been mentioned so much, mostly in regards to the Enclave presence there. The writers could put a twist on it and frame them as the good guys, though after what we've seen them do, it could be tricky to have us emphasize with them.

maybe we should check up on the Chinese and make it in the area like China or Japan make fresh factions could rival the enclave

A place like richmond virgina would be nice since it was the former capitol of the confederacy so there could be a revived confederacy that would be cool also the entire state of virgina would be cool and maybe you could visit dc

If anything the next fallout 100% needs to not be on the east coast, i would really like to see a fallout set in the northwest maybe near canadas border
