i'm thinking about incorporating random "development" cards into a game about classical greek social strife. the "developments" would be in the vein of developments in a historical RTS - basically, things like new institutions (gov't services, new religions, etc.), festivals, declarations of war, etc.
imagine a gm and several players; one pc is a noble, a king, or some other supreme ruler, and the other pc's have various levels of social status. the king would be able to "consult the astrologers" and see what cards are coming up, and then must occasionally draw new ones, like at the start of a season or when someone (who?) rolls a critical fumble or something.
thoughts? anything like this out there, in terms of using a deck of special cards? suggestions of any games about ancient-world social strife would also be appreciated.
