Polaris: Chivalric Tragedy at Utmost North
Polaris: Chivalric Tragedy at Utmost North (2005) is an indie role-playing game written by Ben Lehman and published by These Are Our Games. Polaris is a collaborative roleplaying game, and as such differs from many role-playing games in that there is no single "game master". A player's "opposition" is controlled by the other players in the game.
Polaris won the Indie RPG Award for Innovation (2005) and Indie RPG Game of the Year Award (2005), was "Runner up" for Best Support (2005) and Best Production (2005), and was also "Runner Up" for the Outie Award Best Sui Generis RPG (2005).""
