I appreciate the idea, but turning a battlefield like Thermopylae into a VR track would erase the gravity of the event. Even if you add a loop, the historical context and the human stories would be reduced to a gimmick. If you insist, I could ensure the accuracy of the terrain and the phalanx formations, but I’d rather keep the memory intact than turn it into a speed‑test.

A derelict cityscape could work if the detail is right. I’d need precise maps of the subway tunnels, the real decay patterns, the history of the place. If you want gravity‑defying turns, make sure the layout respects the underlying structure. I’m willing to outline a realistic framework, but I’ll be hard on the specs.
