If this isn't the correct forum for a question about the OGL, please let me know (and accept my apologies!).
Aspiring game designer here, with a question about the use of OGL-licensed materials in my own game. As I understand the license, I am allowed to use Pathfinder and 3.5 content licensed under the OGL in my own, commerically published content, without paying royalties. Is this correct?
If so, am I also correct in assuming I can include character creation rules, and modify the existing game content, as long as the product isn't branded as affiliated or compatible with 3.5 and Pathfinder?
Finally, is it also true that I can license one work under multiple licenses; that is, so long as I clearly separate OGL and non-OGL material, I can retain copyright to portions of my own work, while also utilizing OGL materials?
I realize these are very noob-ish questions. If you can help, thank you very much! <disclaimerese> I of course understand that you aren't in any way providing legal counsel, but simply answering my questions to the best of your knowledge. </disclaimerese>
