"Albedo is a role-playing game based on Steve Gallacci's "Erma Felna: EDF" and "Birthright" storylines, from the funny animal comic anthologies 'Albedo' and 'Critters'. Written by Craig Hilton and Paul Kidd, it was originally published as a box set in 1988 by Thoughts & Images and consisted of 3 books: Player's Manual, Equipment Description, and Referee's Manual; plus the Tlakatan Scenario (sample scenario) booklet."
