Knave 2e Commercial Or Creative Commons

How Knave 2e Licensing Actually Works in Practice

Knave 2e uses a split licensing model that trips people up more often than it should. The core rulebook is available under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 license, while commercial rights are handled separately. This means you can freely download, print, and run games with the book without paying anything. You cannot sell the PDF. You cannot bundle it into a paid product. You also can't take substantial portions of the rules and weave them into your own commercially sold supplement without negotiating a separate agreement. I ran into this squarely when a small press publisher I work with wanted to create a Knave 2e adventure module to sell on DriveThruRPG. They assumed that because the rules were free and openly shared, the assumption that "open means you can sell content built on it" doesn't hold here. The CC BY-NC-SA covers the rule text itself, not a blanket grant to build commercial products on top of the system. What they needed was a commercial license from the rights holder, which is available through Red Patch Games for a fee that scales with project scope. The exact amount isn't published publicly — you email them, describe what you're making, and they give you a quote. For a small 32-page module, it came to somewhere under two hundred dollars, which honestly wasn't bad compared to some other indie TTRPG systems.

Knave 2e Commercial Or Creative Commons — Understanding the Boundary

The practical difference between the two licenses boils down to what you intend to do with the material. If you're running a game for your friends, printing copies for your table, sharing PDFs in a Discord server, or making house rule variants for personal use, the CC BY-NC-SA covers you completely. No permission needed, no paperwork. Just attribute the work and keep any derivative rule modifications under the same license if you share them publicly. If you want to sell anything — a compiled PDF, a print-on-demand book, an adventure module, a setting sourcebook, or even a podcast that heavily references and reproduces substantial rule text — you need the commercial license. The CC license explicitly prohibits commercial use, and "commercial" is defined broadly. Making money indirectly through ad-revenue supported YouTube videos that feature the rules extensively has also come up in discussions within the community, though the exact boundary there is less formally clarified. The safest approach is to reach out to the licensor before you invest significant time in a monetized project. One thing beginners miss: the ShareAlike clause applies only to adaptations of the rule text, not to creative content you produce alongside it. Your original NPCs, maps, monsters, and story hooks you create for a home campaign are yours. The ShareAlike obligation kicks in when you take the actual Knave 2e rules and modify or extend them, then publish those modified rules. Your adventure content sitting next to the rules doesn't get pulled into the license. I learned this the hard way after spending an afternoon drafting a licensing opinion that was way more conservative than necessary because I'd conflated rule derivatives with creative derivatives.

Another counter-intuitive point: you can combine Knave 2e material with OGL 1.0a content without creating a licensing conflict, but you have to keep the portions clearly delineated. The OGL-covered material stays under OGL terms, the CC-covered material stays under CC terms, and you can't blend them into a single indistinguishable block. Some publishers try to merge system mechanics and flavor text so tightly that it becomes unclear which license applies to which section. That's a legal gray area, and the rights holder has not published guidance on how to handle it. When in doubt, separate them cleanly and note which license governs each part. The official downloadable versions are available from the publisher's website and major RPG distribution platforms. Look for the Knave 2e product page, where both the personal use PDF and information about obtaining a commercial license are linked. The commercial license application process is informal — it's an email exchange, not a contract portal with dropdown menus. Expect a response within a few business days. If you're planning a larger project like a book-length supplement or a product line, it's worth starting that conversation early, because the licensing terms can affect your pricing and distribution choices. There are real limitations to this model. The non-commercial restriction means the ecosystem of free third-party content is smaller than it would be under a fully open license like OGL. Some creators leave the system entirely rather than navigate the commercial licensing process. The system also doesn't have a clear pathway for community-created content that stays non-commercial but gets distributed through paid platforms — uploading a free Knave adventure to a site that charges subscription fees has caused confusion, and the license text doesn't address that scenario directly. The conservative interpretation is that any platform where users pay money, even indirectly, could be considered a commercial channel. Again, the rights holder hasn't published a formal FAQ on this.

If you're looking for a similar game system with fewer licensing headaches for commercial use, the basic OSRIC framework or fully OGL-licensed retroclones give you more breathing room. But if Knave 2e is the system you want to use, the licensing is workable — you just need to know which lane you're in before you start building.
