Hi! I love your game system and I wrote an hack woking deeply with your base game system.
Is it possibile to publish an hack of Sledgehammer (it is not a small booklet :P) with the sentence ""Based on Sledgehammer by Gayhalforc. [INSERT NAME HERE] is an independent work compatible with Sledgehammer but not affiliated with Gayhalforc."" and without any commercial purpose under the CC-BY 4.0 licence?
The new derivated game is totally wrote in italian :)
Thanks for this game!!!
