Spent most of my day pondering the logistics and design of a PLP game. One thing I'm rolling around is the idea that a goal is never fully finished- a skill is really always improvable so having a endpoint or place where a player "wins" isn't a good idea. Maybe a circle or an infinity loop. Maybe the final spot will be a reflection point where the player asks if they're done with their investigation or a point for sharing it out.
I also brainstormed up a bunch of cards (tasks) to lead players in different directions.
