The document discusses implementing a skill/technology tree in a game concept. It would require the player to acquire a limited number of tokens to unlock parts of the expansive tree, similar to Total War: Three Kingdoms. This would force difficult choices in which technologies to pursue, reinforcing the theme of player choice and creating lasting consequences. Unlocking technologies could both help and hinder the player's progress, improving replayability and atmosphere by making decisions more impactful. The tree would be called the Night Tree and focus development in areas like science, strategy, stability, support, and suffering.
