That's pretty cool to think about. I think that all the old castles will still be there (unless they crumbled on themselves) with futuristic tech installed here and there.
I'd say something like Carcassone, France or Lisbon, Portugal, but with all of the ancient mix of cutural and architectural styles repurposed and nestled between super-high-rise skyscrapers and mega highways. An actual, medieval castle converted into a night club, it's ancient stones covered in grafitti. Behind it, a steel-and-glass skyscraper rises, it's summit remeniscent of a gothic cathedral.
Definitely Carcassonne, France or Gdansk, Poland
And Toussaint would be situated in South of France, or Italia/Portugal/Spain.
Well, does Cyberpunk 2077 even take place in our universe/on earth?
I'd really like to see that!
It would look like European version of New York city.
the whole USA is European.
Sewers and underground railroad system with parts of the map that have historically been kept exactly as they were in medieval times.
Narrow cobble streets, better looking buildings but not to advance like night city.
Fantastic weather, a lot cleaner than it was in "The Witcher 3" grass and plants growing on the side walk. It must 3 times as big and there must be a park.
