I think that one of the points that must be emphasized in this whole situation is that the original OGL, the one that Dancey created, is not limited to tabletop products, like core rulebooks and campaign modules, as Wizards is claiming. I'll quote Dancey himself, from the link that I shared in the previous post:
Quote: "They also want to assert that the OGL “is limited to tabletop roleplaying content like campaigns, modules, and supplements”.
I am the architect of the OGL, and I can assure you, that statement is not true.
Nothing in the OGL speaks to the nature of products that can use it. That was on purpose. Working on the OGL in 1999 and Y2K our team knew we could not envision all the possible ways it could be used and we did not attempt to enumerate them.
On the other hand, things like computer games, digital objects, novels, web sites, broadcast game content, and similar uses existed in Y2K, our team was well ware of them, and if we had wanted to restrict the OGL from being used in those kinds of projects we could have put such restrictions into the license. We did not."
