Hi everyone. I'm working on a project that is going to use the OpenD6 system and I'm finding some of the legal things with the open game license to be a bit daunting. I understand you can use anything, and change anything, as long as you print the OGL in the book and distinguish clearly what is and is not OGL versus PI. I'm confused on the minutia though. For example, if when describing a skill that is unique to my intellectual property, I mention that you are rolling the attribute Strength with it, does that make that skill now part of OGL because Strength and attributes are OGL?
