       | This weekend at the NYC GPT/LLM Hackathon, we built rpgGPT, a
       | text-based RPG set in the world of Occidaria (think fall of the
       | Western Roman Empire, with a slightly magical twist). System
       | hooks allow the LLM to set persistant game state, and every NPC
       | is powered by the LLM. As you discover other NPCs in the world
       | they are created on the the fly along with an avatar image. We've
       | seen interesting emergent game play. My favorite experience to
       | date was a character, after living through a particularly dicey
       | adventure, decided they deserved the moniker "the Brave". Because
       | the game engine has a rename character hook, that was persisted
       | to the game state. Hope you can try it you!

         | What LLM are you using? How do you save and load the persistent

             | That's a clever way of doing state. For dndinfinity.com, I

             | players are engaged in the following quests") in the
             | prompt, under the theory that it would be able to reason
             | better.
             | 
             | What issues (if any) did you have storing state in json and
             | just plopping that in the context window?

         | 
         | The token limit problem / memory isn't really being handled
         | very well yet. There is some character consistency slippage
         | that does happen with the current mechanism as well so hoping
         | to tackle both of these in next version.
