Licensed gaming maybe, but a license that allows any person to take everything and post it for free isn't a very good license.[/quote
The Open Gaming License didn't do that - publishers who made their books (almost) totally Open Game Content did that.
Some say the d20 glut hurt gaming.
And some say that the OGL helped gaming more than it hurt, even with the "glut."
If the GSL gives authors better incentives than the OGL, I have a feeling it will be better liked. It would certainly allow Green Ronin to make new products without having insensitive people ripping it into an on-line free format.
I don't think that individual authors will care very much about the GSL versus the OGL very much, though companies (and, apparently, fans) will. I certainly doubt that additional restrictions on types of products (and, possibly, on the nature of open content) will create incentives for people to write where they wouldn't have otherwise.
And last time I checked, Green Ronin can do (and is doing) that already with the OGL.
