From RPG description here on RPGGeek:
The era of anthropomorphic animals has arrived ...
MOTARUS is a role-playing game where anthropomorphic animals are dominant. Any time, any place. It is designed to stage adventures from the dawn of time to the pinnacle of space travel - and anything in between. Over 90 species, plus many unusual creatures, are described within this book; and an array of equipment and skills are available. Rare supernatural gifts and abilities are also awaiting discovery for those who dare search for them...
MOTARUS requires a pencil and paper, a full set of polyhedral dice (four-sided, six-sided, eight-sided, ten-sided, twelve-sided and twenty-sided) and this book to play.
