Plans to release a storybook and cassette of the Trigon cycle for the publishing company Rainbow were abandoned after they lost the rights to re-issue their "Star Wars" run which included "A New Hope", "The Empire Strikes Back", "Return of the Jedi", "Planet of the Hoojibs", "Droid World" and "Return of the Jedi: The Battle of Endor" due to poor reflective sales of Buena Vista's "Further Adventure" series overseas which included "Mission to Ord Mantell", "An Ewok Adventure" and "Ewoks: The Battle for Endor". A was released in 1988 for the ZX Spectrum, Amstrad CPC and Commodore 64 by Mastertronic. The game went largely unnoticed and was pulled from production due to licensing rights of the end title theme tune being used. In 1986, Marvel's Star Comics imprint published a "Star Wars: Droids" comic series spun off from the cartoon. The series ran for eight issues. Four issues and issue 5's cover of the series were drawn by John Romita, Sr. The "Lost in Time" crossover story from "Droids" #4 was continued in an issue of "Ewoks". The last three issues are part of an arc recounting the original "Star Wars" film from the droids' point of view. Additionally, Spanish comics publisher Editorial Gepsa produced two-page "Droids" comics as part of an anthology series. Along with "Ewoks", the entire series has yet to be released on home video. Some episodes were released on VHS in the 1980s and 1990s, most notably the UK PAL releases over four cassettes ("Droids" 1–3 and "The Great Heep"), which had the opening sequences and credits edited out. In 1996, Rick McCallum produced "The Pirates and the Prince", a direct-to-video movie compiled from four episodes, and while working on the "Star Wars" prequel trilogy, expressed hope for an eventual release of the series on DVD. In late 2004, McCallum produced a DVD titled "Star Wars: Animated Adventures – Droids", which featured "The Pirates and the Prince" and "Treasure of the Hidden Planet", a new compilation film including narration from Mungo Baobab (voiced by Alex Lindsay). Both titles included some soundtrack changes. McCallum retired from Lucasfilm in 2012, making the future of its release uncertain. According to David Perlmutter, compared with "Ewoks", "Droids" "was rudimentary, with short enough story lines for as many as four narratives in a single episode.
