Many of the interactions in RDR2 are quite mundane, and despite thousands of hours of (high quality) voice acting, it can become quite repetitive.
I could very much see those micro-interactions being LLM generated, but the TTS would need to be a step above where even the best models are now to come close to RDR2s production quality.
It might indeed fail to reveal something it should but even that i think is unlikely if the harness steers it hard enough.
I think it could be fun. If you're always given 4 choices of what you can ask the NPC then your choices can be too obvious. If its open ended then you have to think a little what to say and ask.
Like a remake of a game
e.g. let's say an important character dies in your game but that hasn't happened yet in this point in the story. You're talking to some NPC. That NPC can't possibly spoil that that character is going to die because the developer wouldn't feed that in as context. The NPC doesn't "know" the character is going to die. You, as the player, might be able to convince the NPC that that will happen and it might respond accordingly, but it won't just randomly divulge that by accident.
What you're describing isn't bad dialog, it's bad interaction design.
I think your mental model might be of a single session with zero state, and no bounds on topics of conversation outside of the character's backstory. That isn't close to how this would work. A little understanding of how the game currently operates and some imagination, and you'll see how it could be improved further without degrading gameplay.
> those games would be made popular by people breaking the LLMs in funny ways
Because making the game do funny things didn't happen with RDR2, or any other game, device, or indeed humans (there are whole genre built around making people do or say "funny" things).
> What you're describing isn't bad dialog, it's bad interaction design.
I didn’t say it was bad dialogue. It should be pretty obvious that’s not the argument since I talked in terms of feature VS bug.
> Because making the game do funny things didn't happen with RDR2, or any other game, device, or indeed humans
Again, not at all what was said. Of course those things happen, and of course I know that. The clue is in the fact that I brought it up, which can be ascertained by reading the comment and engaging with it in good faith. The point was that becoming the focus.
