So you want to write something that’s compatible with External Containment Bureau? You’ve come to the right place! We’re offering an open license that will let you make and sell your own works that build on the game (or stand completely on their own), under the terms below. We can’t wait to see what neat new REDACTED MATERIAL the community creates!
The Short Version
The legal language of the license is what’s binding, not this explanation, but in short you can use the text of External Containment Bureau in creating new RPGs or new supplements for External Containment Bureau as long as:
- You give us credit
- You offer the new text that you create under essentially the same license so that others can build on it, too
To avoid confusion, we ask that you not include “External Containment Bureau” in your title, though you are welcome to describe your work as compatible with or intended for use with External Containment Bureau.
You do not have permission to imply that any of us endorse your work, nor to use the Mythic Gazetteer logo.
However, scroll down for a handy “REDACTED MATERIALS” logo you can use to identify your work as building on External Containment Bureau!
License to Use the Text of External Containment Bureau
The text of External Containment Bureau (not the art) is offered under a CC BY SA 4.0 license, meaning that you are free to distribute the text and to adapt it within the scope of the license, which requires that you give us credit and that you share your adaptations under similar terms. Please credit the authors, Lexi Antoku, Eric Brunsell, Michael Elliott, Justin Ford, and Eli Kurtz, and the publisher, Mythic Gazetteer LLC. The text of External Containment Bureau is additionally offered under a license having the terms of CC BY SA 4.0, except: (1) if the Adapted Material is a literary work (such as an RPG book), then the Adapter’s License need only be applied to the text (not, for instance, illustrations) and (2) you must include this and the following sentence in your licensing terms. The CC BY SA 4.0 license is available at creativecommons.org/licenses/by-sa/4.0/
What’s this ‘additionally offered’ license stuff?
Some people have expressed concern that the sharealike provision in CC licenses could be read to require that the art in a subsequent book be licensed out and not just the text. That’s not the result we want. The extra language beyond just the vanilla CC BY SA 4.0 license is intended to make it clear that when you publish a work like an RPG book or supplement, you only have to offer the text under the open license.
How should a new work credit ECB?
Wherever you put your own copyright info, add the following text (in the same size as your other copyright info):
“This work uses material from the External Containment Bureau roleplaying game (found at https://mythicgazetteer.itch.io/external-containment-bureau), designed by Lexi Antoku, Eric Brunsell, Michael Elliott, Justin Ford, and Eli Kurtz, and published by Mythic Gazetteer LLC, pursuant to the open license available at mythicgazetteer.com/redacted-material.”
How should a new work comply with the sharealike provision?
That’s a question for your lawyer (which we are not), but feel free to use our language as a model:
The text of this work is offered under a CC BY SA 4.0 license, meaning that you are free to distribute the text and to adapt it within the scope of the license, which requires that you give us credit and that you share your adaptations under similar terms. The text of this work is additionally offered under a license having the terms of CC BY SA 4.0, except: (1) if the Adapted Material is a literary work (such as an RPG book), then the Adapter’s License need only be applied to the text (not, for instance, illustrations) and (2) you must include this and the following sentence in your licensing terms.
