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.
