Based on Anime and/or Manga
- The defunct Guardians of Order released various licensed anime Role-Playing Games as the "first edition" of their Big Eyes, Small Mouth RPG system. By the time the company had closed, they had made RPGs for: Sailor Moon, Hellsing, Slayers (interestingly, they released it both in "Tri-Stat" and d20, but the latter was not a worldbook for the d20 version of Big Eyes Small Mouth, instead being a fully independent game), Dominion Tank Police, Tenchi Muyo!, Trigun, and Demon City Shinjuku. All of these games included a lot of additional information of their respective shows, including an up-to-date episode guide up until the time the books were released.
- Log Horizon has it's own RPG that goes by LHTRPG with the character Seine, from one of the sessions, making it into the anime as a Canon Immigrant.
- R. Talsorian Games released an official Bubblegum Crisis Role-Playing Game, which stands out because it included a full "episode guide" for both the original OAVs and the "Crash" continuation, as well as providing a large number of stats to items that could be considered "Expanded Universe"—a large number of sketches and notes that the creators had done but had fallen under "What Could Have Been".
- R. Talsorian also released an official Dragon Ball Z RPG.
Based on Comic Books
- Albedo: Erma Felna EDF had two RPGs: Albedo the Roleplaying Game self-published in 1988 by Steve Gallacci with Paul Kidd writing, and Albedo: Platinum Catalyst by Sanguine Publications in 2004.
- The Usagi Yojimbo Roleplaying Game by Sanguine Publications, using a variant of the Cardinal system used in Ironclaw.

The new edition will be published by EN Publishing.
- Yet another Mongoose Traveller campaign setting was based on Strontium Dog.
- Green Ronin Publishing's The Red Star RPG, which used the d20 Modern system and had extensive information on the Red Star universe that had not appeared on the comic, plus original art by the writer/artist (and creative consultant, hence the expanded universe information), Christian Gossett.
- Also by Green Ronin Publishing, the third edition of Mutants & Masterminds first saw the light of day as DC Adventures, which provided official stats for many DC characters and information on the DC Universe up until shortly before Flashpoint.

Based on Film
- Ghostbusters, based on Ghostbusters, was the first pen-and-paper RPG to use dice pools.
- Serenity Role-Playing Game, based on Serenity. As an interesting note, the company (Margaret Weis Productions) had only the rights to Serenity (meaning that the events of the Firefly series could only be talked about in very Broad Strokes terms within the book proper), yet nevertheless it obtained high acclaim while it was in production. The "second edition" of this game was made using the Firefly rights proper (which, ironically, means that the events of Serenity are the ones getting the Broad Strokes treatment).
- Mongoose Publishing released the official Starship Troopers Roleplaying Game, using the D20 System that was employed on the Third Edition of Dungeons & Dragons. Interestingly, the game was an official Patchwork Fic, using the Starship Troopers cartoon as a baseline and grabbing from the film and original novel liberally for additional details (for example, the version of the Mobile Infantry that appears on the movie was designated as "Light Infantry" in the game and justified as people going accelerated training in order to bolster the Mobile Infantry's numbers for the Klendathu assault—the book's "Cap Infantry" then becomes the power-armored soldiers from the cartoon, who could specialize in heavier power armor (the book's "metal gorillas", represented by the cartoon's Mini-Mecha and two heavier power armor variants that were added later on)).
- Army of Darkness got a Unisystem RPG.
