Some people are “regular customers/citizens”, others are “algorithms”.
Each algorithm has the same goal: get the citizens to engage with YOU more than anyone else.
The citizens have personal goals that indicate “desires” or “preferences”, such as “view as much RED CARDS as possible” or “buy as much JEWELRY as possible”.
In the end, multiple players can “win” (by achieving their personal goals). But maybe there’s a final signifier/condition that creates a SINGLE winner if you want.
EXTRA IDEA: All of this is secret. (Why would another algorithm/platform know about stuff going on at YOUR place?) But a core part of the game is SELLING DATA to each other. Giving this information so others can guess someone’s “desire” or “algorithm” too.
EXTRA IDEA: The algorithms can have secondary goals too. “Show the most ads” or “sell the most stuff” or “show only positive things about topic A” or whatever.
