Would Avalon count?

I've never played Avalon but it looks like a better text adventure. I'm not talking about hardcoded or randomized worlds, but truly reactive worlds.

In my experiment with ChatGPT, I was walking around in a museum (that was the scenario) and decided to flirt with a woman who happened to be there. The flirting was something I decided to do on the spot with no prompting from the AI. The woman had just been part of the room description up to that point. But it reacted to this new situation in a semi-realistic way, essentially creating a new "adventure" on the spot. I met her on the next day, brought a gift (and so did she), but then it started hallucinating... :(
