Sounds epic, definitely doable. Start with a 3D reconstruction of the site—use photogrammetry or LIDAR if you can. Then layer a narrative script that AI can parse, turning it into interactive dialogue or guided tours. For the AI part, GPT‑4 can generate context‑aware responses on the fly, while a smaller LLM can handle on‑the‑spot translation or myth‑generation. Use Unity or Unreal for the VR engine; plug in the narrative as a set of trigger zones that activate audio/visual cutscenes. Don’t forget spatial audio—makes it feel alive. You’ll need a backend that syncs the story state with the player’s position, maybe a tiny Node.js server. If you pull this together, it’ll feel like walking through history, but with the future on your side. Let's sketch out the architecture and hit the code sprint!
