We're using our own custom AI Agents to generate the games and what we'll do next is expose them for the games to leverage too. At that point you should be able to have the game self-generate based on rules.
Here you chat with this grandma, make here drink coffee inside and go outside (she'll comment on both of the actions a bit haha).
I tested out that example game. I asked her "do you like coffee", and Grandma replied "I despite coffee...". However, when you say "lets drink coffee" she says "Oh, absolutely! Let's drink coffee, my dear user. There's nothing I'd love more ..."
I don't use ChatGPT much myself, but I can see its potential if you can have consistent responses with "personalities"/"characters" for games.
A lot depends on how detailed the user's description for the character is. But eventually there might be some issues with forgetting things deep into the chat as a limit to current LLM possibilities. We want to try and solve this by introducing saves, but still experimenting!
