The “algorithm” or “generator” as we call it, was used only as a solid base for further development of the scene. It was a shortcut, a tool, but never a goal. More of a production-related thing. It created a rough first pass through a scene, which was always tweaked and adjusted by hand - in all 1463 dialogues. In many, the algorithm wasn't used at all, as they demanded custom approach from the very beginning.
Every cinematic dialogue was approached with the same care, attention and goal - to create the most compelling and emotional scene for given quest and story. Only this way, the characters could ring true and players would want to invest in them, to understand them, to help or condemn them. When they act like humans, not voiceover-delivery machines. Achieving this is a deliberate, careful process.
