LLM Game Engine Bridges AI And Narrative Games

A new LLM Game Engine framework bridges traditional narrative engines (Ren'Py, Twine) and AI chat interfaces by combining a causal graph and stat system to enforce deterministic story progression. Built in Python 3.11 and using Anthropic's Claude Haiku for the classifier loop, it includes an example 'escape_room' story and JSON-based story formats. The design preserves free-form player input while only matched actions and bounded ±5 stat changes advance the narrative.
