User summary Supplement produced by the Italian magazine Anonima Gidierre: this product is an RPG rule set of its own. Zoodiak is presented as a "meta-RPG": as such, it forces the players involved to dump their usual playstyle and take on the mindset assigned to each one depending on their zodiac sign, ascendant and planetary position: as such, Zoodiac cannot be played on its own but always needs to be played in association with another RPG. What Zoodiac changes is a player's reactions and playstyle, not an adventure's plot nor an RPG's rule system.
