Joining Paizo (which has hinted at plans to update Pathfinder), Kobold Press (with it's Black Flag project), MCDM (which is working on a new game), and--of course--Level Up: Advanced 5th Edition (which was released last year), Cubicle 7 has announced a new C7d20 System.
You heard it here first! C7d20, our brand new system, is in development. Building on the great d20 games we know and love, our system will offer all the exciting action-packed adventures players expect from a d20 fantasy game, as well as the broader styles of gaming that we’ve brought to 5e in Doctors and Daleks, Adventures in Middle-earth, and Uncharted Journeys.
C7d20 will be a complete rule set that is compatible with 5e — you’ll be able to use all of your favourite 5e books and supplements, including Uncharted Journeys and Broken Weave. A core rulebook for C7d20 will launch later this year and you’ll be able to see hints of what is to come when Broken Weave launches. We’re involved in discussions about open licensing and will have more news on this as the situation develops.
