Rules
Your work can use any of the game system rules and game terms found in the current edition Traveller books published by Mongoose Publishing.
Settings
You are allowed to use the Traveller setting as presented in the current Traveller edition books published by Mongoose Publishing as well as any Mongoose-published book covering the official Third Imperium setting (for example, Spinward Marches). This includes the names of all characters, races, and places and all gear, equipment and vessels; the capitalized names and original names of places, countries, creatures, geographic locations, historic events, items, ships, and organizations presented in those books.
To be clear, the setting of 2300AD is not open for use at this time.
Allowable Media
Roleplaying game materials only.
No fiction except short vignettes in an rpg work
No software or comics
Mongoose Publishing follows DriveThruRPG and Roll20 Guidelines in regards to AI Writing and Editing. Update July 19th, 2023: While we value innovation, starting on July 31st 2023, Roll20 and DriveThru Marketplaces will not accept commercial content primarily written by AI language generators. We acknowledge enforcement challenges, and trust in the goodwill of our partners to offer customers unique works based primarily on human creativity.
Art
No art can be used from Mongoose publications (or any other Traveller publication). Art packs containing art that is allowed to be used in community content works may be made available by Mongoose to TAS creators.
Mongoose Publishing follows DriveThruRPG and Roll20 Guidelines in regards to AI-Generated art. Update March 24th, 2023: The following policy applies to DriveThru Marketplaces, including Community Content Programs and Supported Marketplaces. DriveThruRPG defines “AI-Generated art” as images created through the use of artificial intelligence algorithms and techniques trained on pre-existing data sets. (Examples: Midjourney, Artbreeder).
- At this time, DriveThru Marketplaces require partners to set their own AI-generated artwork policies on Game, Rulebook and Adventure products. Any products that utilize AI-generated artwork must be tagged as such.
- At this time, DriveThru Marketplaces do not accept standalone artwork products that utilize AI-generated art.
Titles that do not comply are subject to removal from the marketplace. Repeat offenders may have their publishing permissions revoked. A full statement of intent regarding our policy update can be found here.
There are many resources available here, most for free.
Logos and Trade Dress
You are encouraged to use the TAS logo on the cover of your title.
If the cover of your title shares the trade dress of official Traveller titles, then the TAS logo must appear on your cover prominently enough to be discernible even at cover thumbnail size (the size of cover images as seen while browsing DriveThruRPG).
You may not use any other Traveller or Mongoose logo.
Creator Templates
You are encouraged (but not required) to use the template(s) found [here] when creating your work.
You can find more information on templates here.
