An interesting game called "Leaky World" attempts to turn Wikileaks founder Julian Assange's essay on conspiracy ("Conspiracy as Governance") into a web game.
In the game, players are tasked with connecting dots between political powers - show as red dots on a world map. As lines are connected between these red dots, some begin leaking information. These leaks appear in the game as new headlines. The goal at this point in the game is to sever ties with the source of the leaks.
Of course, it is a bit more complicated than that. Check out the game for yourselves at www.molleindustria.org.
