THE MECHANICS

Sig focuses on collaborative narration and difficult decisions. When two participants propose different outcomes to a situation, each participant rolls dice, adding in bonuses if they have applicable Talents. The participant in the conflict with the highest score gets the desired outcome and must pay the Price of Victory.

Players gain Influence by confronting their Beliefs, and they use that Influence to shape the world around them and encourage each other to grow. As the player characters change, so too does Sig; the city’s tethers to different planes of existence shift and reorganize, changing the fundamental nature of the city itself.
