Eric M. Lang and Bruno Faidutti have joined forces to create the ultimate prisoner's dilemma game. Do you cooperate and risk getting outsmarted by a greedy player? Or do you compete and risk losing everything? You are pirates who just looted a ship and must negotiate how to split the treasure. There are seven types of loot with values from 1 to 3. At the end of the game, you only score the treasure types you have the most and least of.
