Exactly this. I want plot/character driven games like RPGs to be a curated & carefully designed, plotted, and paced experience. I want speech & narrative to be scripted! It means someone sat down and thought about the experience it produces for the player. It means a real voice actor has performed it, putting the right emotion and pacing into the line. I don't want AI generated stilted dialogue, uncanny valley speech…
You want your NPCs to be limited in their conversations, to only follow a set few paths, if you think of a way to play the game that's not been anticipated years ago, you don't want that to be possible
