Hi, I’m reading your OSR retroclone for solo. You write: “This version is licensed via Creative Commons: CC BY-NC-SA I’ll choose a different license once ORC licenses are out and I can compare.” Well, you can’t. Even if you try to emulate WotC, the CC license is irrevocable. And I don’t know (and don’t care) about the new ORC license, but it will be more restrictive than CC for sure. So, no you can’t change the license. Legally… Except it you change it for another CC license which is even more open than the CC BY-NC-SA. FYI. Regards. P.S.: I don’t care about the ORC license because there are tons of open licenses out there, such as the CC, and any attempt to create another one from scratch only makes me suspicious. You cannot reinvent the wheel.
