Could you build this?

No Simulating a dynamic world with nearly 7,000 persistent historical NPCs, complex economic simulation loops, and scalable LLM dialog generation across lifetimes requires extensive game engine engineering, AI cost optimization, and game design expertise.

What it would actually take: This requires a custom game engine or sophisticated Unity/Godot architecture combining entity-component systems (ECS) to simulate thousands of autonomous agents, localized economic ticks, and aging systems. The narrative AI requires advanced context management, prompt caching, long-term memory retrieval (vector search / episodic memory per NPC), and fine-tuned low-latency local or batched LLMs to keep token costs and latency manageable. Designing balanced, historical RPG mechanics at this scale demands veteran game design and systems programming talent.
