So much fun as it picks up any custom setting, from historical countries to Imperium from Warhammer 40k, and even party house with friends. I was even able to make it write everything in different language by asking for it in description. Sorry for eating big number of credits, tho. It becomes a bit stale as there is only 4 parameters and no custom flags, but it is great proof of concept that LLM could take reigns of game mechanics. I am a bit disingenuous - AI sometimes mentions past decisions, but it only affects the narration. Can't wait when in future LLM would bake a whole plot with cumulative story where past choices not just shape the story, but also intertwine in meaningful way. But it would probably require whole location simulation with NPC's.
