Created by John Wick, you take the role of nobles with land and peasants as opposed to dirty adventurers. Gameplay focuses more on the social and politcal. The system is unique in that you don't roll for success or failure. You roll to take control of the narrative. For example, if you attempt to jump from roof to roof, you would take a "risk" and set aside some if the dice as wagers. If you roll hits a target number, you get to dictate what happens plus a nmber of details equal to your wagers. So you might say
"I miss the other rooftop. I fall onto the balcony below. A servant walks by and lets me in."
If you had three wagers and a successful role. A failed role doesn't mean you fail, just that the GM dictates what happens.
Fighting has more specific rules to keep things in check but that's the basic idea.
