User Summary: Series of second party products for Mutants and Masterminds. Can be identified through the M&M Superlink logo.
From the publisher:
Since the release of the Mutants & Masterminds RPG, we've had a lot of requests from people who want to publish compatible material. One sticking point is the Open Game License itself. It specifically prohibits you from claiming compatibility with other Trademarks (like Mutants & Masterminds) without entering into a separate agreement with the Trademark holder (Green Ronin, in this case). We are not willing to just give away the Mutants & Masterminds logo to anyone that asks, as we have worked hard to make it a mark of quality. Nor, however, do we want to shut down the creation of compatible material using the Open Game License. M&M wouldn't exist without the OGL after all. Our solution to this: M&M Superlink.
M&M Superlink is a logo that publishers can use to indicate compatibility with the M&M rules. Using it is pretty straightforward.
1. E-mail superlink@greenronin.com with a short query. Just a few sentences on what you want to do and when. This is basically to give us a heads up on your plan and to head off misuses of both licenses at the pass. If your proposed product follows the OGL and doesn't violate M&M's Product Identity or protected content, we'll give it a green light to proceed.
2. Once your product is ready to go to print (or for release, in the case of PDF-publishers), send us a low-res PDF of the whole job for approval. We will not be approving content per se (i.e. we're not going to check your math on stat blocks, tell you feats are unbalanced, or take issue with your backstory) but again checking to make sure you have used the licenses correctly. We will try to review such submissions within a week, schedule permitting (in other words, if we get something the day before GenCon, don't be surprised if you have to wait). Once the item is approved, we'll send you a high-res version of the logo and appropriate legal language to put on the credits page. If not, we'll tell you what you need to fix and then you'll have to resubmit.
M&M Superlink is a free license, in keeping with the OGL itself. We will keep this section of the website up, so players new to the idea of open gaming can learn how it works.
