Rules: only places that don’t exist, so no “NY from Spider-Man” also if you can limit to a building or little town, not an entire city or map.
My pick: The Spencer Mansion from 1996 Resident evil. I always loved that place. Of course without the creatures.
Well I guess that disqualifies Belle Epoque Paris from AC Unity.
Would love to visit the space station from Prey. On the condition the Typhon have been exterminated of course. It’s such a beautiful map and I loved cleaning up my makeshift base of operations in the main lobby.
