Retro RPG: Usagi Yojimbo
These two Usagi Yojimbo Role-Playing Games are based on Stan Sakai's Eisner-award-winning comic-book series Usagi Yojimbo. The first was written by Greg Stolze and published in 1998 by Gold Rush Games. The second role-playing game to be published is written by Jason Holmgren and Pieter van Hiel, published by Sanguine Productions in 2005.
The games are set in a fantasy version of Japan in the Edo period (beginning of the 17th century), the first version is based on the Fuzion rule system, and the second version uses a heavily modified variant of the systems used in Sanguine Productions' other role-playing games Ironclaw, Jadeclaw, and Albedo: Platinum Catalyst.
