The problem is the issue of derivative works.  Does constituting monster stats block from a CC-BY-SA licensed RPG into an adventure make it a derivative work of that RPG? If it does then it has to be CC-BY-SA per the legal text of the license. If it doesn't then only the Monster Stats need to be declared as CC-BY-SA. In contrast the OGL make it clear that only the Monster Stats need to be open content. The ORC license makes it clear as well that ANY game mechanics must be Licensed Material (open content). So again only The point of these license is so that a layman can use them without hiring an IP attorney. The CC, OGL and ORC try to achieve this by providing clarity. The OGL predated CC and started a tradition of making a distinction between open content and product identity. ORC continues that traditions with the distinction between the three different types of material, Licensed Material, Reserved Content, and Third Party Reserved Content. CC in contrast is silent and thus not clear what you do when you are intermixing two different types of content with two different licenses or where part of the work is not licensed. Leaving it up to the author to figure it out.Of course, all of these issues are avoided if you declare your entire work as open content. Which is what I do for my stuff that wasn't licensed by other folks like Judges Guild. The text and maps of Blackmarsh are dual licensed under the OGL and CC-BY. And the entire text of my Basic Rules for the Majestic Fantasy RPG is licensed under the OGL. And going into the future I will be licensing my material under OGL, CC-BY, and ORC (your choice which one to use).  It is only when people don't want to share fully that we get these questions.</blockquote>
