Of the many applications of AI in games, I am more interested in those that can unlock new form of experiences. First thing that comes to mind is narrative, of course, but since as a developer you are paying for hosting a server with an LLM I think you need to focus more on the return of the investment on that infrastructure.
One idea is to have new forms of special offers related with the fact that you can or cannot engage with certain systems within a game. Maybe you played heavily during the last event, but you have no time this week. You can say it, and the system can find special solutions for you. Just one example.
