Universalis

Universalis is a role-playing game (RPG) from Ramshead Publishing that stresses interactive storytelling. The game uses a unique system, based on "coins" that are used to make additions to the game, which allows the entire group to participate in the creation of the setting and events in play without a traditional gamemaster. The rules also provide a means of negotiating their own alteration, allowing for unlimited customization for play. The system is meant to support any possible genre.
