I believe, in fact, that it is even a bit more restrictive than people are seeing. It is not just that you cant mix the two licenses in one product. It is that if you use the
GSL you cannot also use the
OGL for
3E products.
In other words, publishers have to decide if they want to stay
3E or if they want to come along for the
4E ride.
It is not a product by product choice. It is a business by business choice. It is not "well, this product will be
4E using the
GSL but the next one will be for
3E under the
OGL."
In other words, Necro cant do 3 books for
4E then decide to go back and do a
3E book.
Or, along the same lines, if Paizo wants to do Pathfinder
3E, it cant do
4E products. If it does, it can no longer do
3E ones.
I have, however, specifically clarified that Necro can do
4E and Paizo can keep doing
3E Pathfinder stuff and that is just fine.
Once you are in for
4E, you are in, and cant go back (well, you could but you would presumably lose the right to use the
GSL from that point forward).
I have to clarify if I will be able to do
3E stats as seperate downloads for
4E books. My guess is that I will not be allowed to do that under the
GSL. But I havent asked that direct question.
By the way, this info was from Wizards. Unless I am misunderstanding what they told me or they didnt understand my question, this is how it will be.
