Very interesting project! I cannot resist mentioning an old project of mine that was made in a very similar spirit, but way before any LLM: wrapping a classic Lone Wolf gamebook around a very crude text parser: https://projectaon.org/staff/christian/gamebook.js

I had written an entire "framework" for it, in JS (so in theory more books could be supported), but it never went anywhere: https://github.com/cjauvin/gamebook.js
