Free League Publishing today officially released an open game license for their new original sci-fi RPG Coriolis: The Great Dark, allowing community creators to publish material for the game freely, without paying royalties. The license text, and the special logo to be used for the third party publications, are available at the Free League website.
"Our vision for Coriolis is for the game's boundaries to be as vast and endless as space itself," says lead designer Kosta Kostulas. "We can't wait to see what stories and worlds the Coriolis community will build."
Free League previously has open game licenses for the award-winning Dragonbane fantasy RPG and the Year Zero Engine game rules system. Dozens of products have been successfully published under these licenses, some of which are listed here and here.
As with the previous third party licenses, the Coriolis: The Great Dark community content license is royalty-free and irrevocable, meaning that it can be updated, but creators will always be able to use any published version. At this point, the new license only covers Coriolis: The Great Dark, not the previous edition Coriolis – The Third Horizon.
The star portals are dead. Ship City is dying.
But there is still hope.
