There are a lot of games and gamers I guess that would benefit from very dynamic dialogue. It would mostly focus on long term games where the feeling of immersion in the world is valuable long after completing the main quests. Or systemic games where the main focus is concrete systems gameplay, but dialogue could help with idle chit chat and immersion.

Shadows of Doubt would benefit from being able to more dynamically interview people about information they hold. Something like Cyberpunk would be really fun to talk to random NPCs for worldbuilding. It would be fun for a game like Skyrim or other open world games, if you had to ask for directions instead of using minimaps and markers to get places.

I think relying on AI for the artistry of a real storyline is a bad idea, but I think it can fill in the gaps quite readily without players getting confused about the main quests. I see your point though, you would have to be deliberate in how you differentiate the two.
