IMO this isn't going to be fun for most once the novelty wears off. Games are goal oriented at the end of the day and the great games are masterfully curated multi-disciplinary experiences.
I'd argue throwing a game wrapper around an LLM is a new LLM experience, not a new game experience.
I think the people that are for this development are thinking more along the line of a game designed from the ground up to include AI LLM interaction.
Once someone decides that will be a critical and fundamental part of a AAA game, the rest can be worked out despite what will be I am sure many unintended emergent behaviors.
