The closest thing to this I know of is The Forgotten City. It has some fantasy elements and the city itself isn't a real one. Premise: "The Forgotten City is a narrative-driven time loop adventure in ancient Rome. Discover the ruins of an ancient underground city, travel 2000 years into the past, and unravel the mystery of who destroyed it by cleverly exploiting the power to wind back time. The fate of the city is in your hands." Developer comment on historical authenticity: "In terms of historical authenticity, we engaged two historical consultants: Dr. Philip Matyszak, who has a D.Phil from Oxford and teaches at Cambridge, and has written 17 books on the ancient world. And Dr. Sophie Hay, who has spent 20 years excavating the ruins of Pompeii. Dr Matyszak helped us to create a game world with historically authentic art, architecture, costumes and customs. And Dr Hay helped out with a comprehensive review, ensuring our architecture and art was consistent with her observations of Pompeii, which was preserved in a very similar time period. We spent over 20 months on this and exchanged 300+ emails and did video flythroughs."
