A lot of the characters’ and setting’s history is created by the players. You don’t use dice but two decks of playing cards, one for the Sensei and one for the players. Most actions can be merely narrated; you only use the cards when it’s time to take risks (“Gambit”) or fight (“Duels.”) At first, the system is disorienting for those of us used to dice; it looks like no other role-playing game I can think of.
Of all the RPGs I’ve played that used standard playing cards to resolve actions, this has the most enjoyable, tactical and interesting system. It blows the ones in Hillfolk/DramaSystem or Prime Time Adventures out of the water, for example. It’s not just a matter of having more cards, or higher cards; a lot of strategy can go into deciding when to escalate or concede, in order to save an advantage for later.
