1, 5, in that order. 5 nets you 2, more or less. WotC didn't embrace the OGL when it was new; they're not going to leap into it now.

And I am answering back with a question: what are you suspecting I am getting at? Because if you were not suspecting something you would not make the question. The OP is pretty simple and straightforward.What I'm interested is: what is the OP getting at?
