 Watership Down inspired the creation of Bunnies & Burrows , a role @-@ playing game in which the main characters are talking rabbits , published in 1976 by Fantasy Games Unlimited . It introduced several innovations to role @-@ playing game design , being the first game to allow players to have non @-@ humanoid roles , as well as the first with detailed martial arts and skill systems . Fantasy Games Unlimited published a second edition of the game in 1982 , and the game was modified and republished by Steve Jackson Games as an official GURPS supplement in 1992 .
