Storm Raven said:The biggest issue for WotC here is likely to be the OGL, although a lot of people have, I believe, an overly expansive view of what it covers.
I agree. The copyright issues concerning games are already more complex than, say, a piece of artwork or a novel because game rules are given special treatment. Adding in the OGL, which covers a massively complex topic in a very short space and without a great deal of detail, makes things extremely muddy. Despite the fact that the OGL is actually quite simple to understand when someone is using it for its intended purpose (to produce material supporting or slightly modified from the original rules) the license is actually quite vague on some points and the language can easily be interpreted to give publishers a much broader set of rights than what might have been originally intended.
Fortunately, it seems that WotC is content to allow people to push the boundaries of the OGL. For me, this has done more to cement my goodwill toward the people there than any product they've produced themselves. I imagine the goodwill garnered from this generous attitude toward OGL publishers is worth much more to them than whatever damages they might receive or economic benefit they might gain from crushing every small project based on a liberal reading of the license.
