Sounds like a neat algorithmic puzzle: detect the player’s micro‑behaviors, map them to a state machine, then re‑wire the script on the fly. The trick is turning affective cues into clean, actionable variables—people are messy, not always in neat patterns. If you can nail that translation, you’ll have a narrative that feels alive, but you’ll also have to watch out for over‑optimization: a pattern engine can turn a good story into a predictable algorithmic loop. Keep the data clean, the rules flexible, and maybe throw in a random seed or two to avoid pure determinism.
