How is this different from https://github.com/AkshitIreddy/Interactive-LLM-Powered-NPCs ?
This should cover all you need to make an NPC a bit smarter (but it is still "scripted").
LLMs are not what you would use to make a bot in Civilization, or Age of Empires.
The generative AI/ML scene seems to be very meme-y, from that, to all of the anime related stuff, to Mistral releasing models as torrents with warez-scene style .nfos, etc.
