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.
oh my god, Vvardenfell, absolutely. the volcanic island from Morrowind
I’m old and I still imagine being a Telvanni mage when I’m having trouble falling asleep
Don’t forget to cast feather fall if you want a glass of water in the middle of night.
