License Terms (sounds official!)
Let’s get all the boring stuff out of the way first.
This work is licensed under a Creative Commons Attribution 4.0 International License. That means that you can copy and share any part of this document—or even the whole thing!—in whatever format you choose. You can build on it, hack it, translate it, remix it, bop it, twist it, pull it, whatever you feel like. You can even make money off of it! I mean, you can try, anyway.
What do you have to do in order to get all that cool stuff? Well, this is the least restrictive Creative Commons license there is, so all you have to do is give appropriate credit, put a link to the license somewhere in your stuff, and say that you made changes to the material (which you probably did).
What’s “appropriate credit”? Wherever you put your own copyright notice in your work (or wherever you like if you don’t put one in) add the following text:
This work is based on the Powered by Moose and Squirrel SRD (https://majcher.itch.io/powered-by-moose-and-squirrel-srd), product of Marc Majcher and Majcher Arcana, and licensed for our use under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).
(If you’re publishing on the computernets, feel free to be extra cool and add links to https://majcher.itch.io/powered-by-moose-and-squirrel-srd, https://creativecommons.org/licenses/by/4.0/, and https://majcher.itch.io/ to the appropriate places instead of writing them out.)
If you use the sweet Powered by Moose and Squirrel logo in your game (and you totally should), add the following text:
The Powered by Moose and Squirrel logo is © Marc Majcher, and is used here with permission.
You’re free to color or resize the logo however you like, but it shouldn’t be materially altered in any other way. Just be cool, man.
Additional Limitations (I knew it!)
The official text of the Creative Commons license says that you can’t add any extra legal limitations, but I’m gonna add some more stuff here anyway. It’s clearly not legally binding in any way (and lawyers are expensive, and a luxury that I’m really not interested in ever investing in—buying RPG books is a much better use of my money) but the most important part of the licensing here is “just be cool, man”, so don’t be uncool. I’m not gonna come after you, but it’ll make me sad, and the world is already sad enough.
You can’t imply that Marc Majcher, Majcher Arcana, Gizmet Gameworks, the Euodyne Immersive Collective, or any other goofy name I’ve made games under are endorsing you or your work unless we worked something out there. Don’t use those logos or other copyrighted stuff without getting permission. (But you can use the PbMaS logo up there, of course.)
You can’t do anything with this SRD that would be damaging to Majcher Arcana or Marc Majcher’s image or reputation. (Like, for real, I don’t think you could, even if you tried. But don’t try.)
And finally, for really real, I really freakin’ mean it: nazis, homophobes, racists, transphobes, and other species of bigots are expressly forbidden from making new content with the Powered by Moose and Squirrel SRD. If you have to ask if this includes you, take a good long look in the mirror, because it probably does.
