The answer is that right now he is just a mad king...so no preferences. But then poetry can be subjective. My plan is to continue working on the game and give him things that he values together. So grouping words into longer vs shorter words, or like subjectively harder vs softer or warmer vs cooler words and giving him a day by day preference based on that. Ultimately I think it will still come off as...random, but the goal is to have a hidden rule with it.
