The OSR owes them nothing
. Not the Forge in general, or Ron Edwards as its architect in particular.
Even the arguable resurgence of self-publishing in the last decade was not 'thanks to' the Forge, it was thanks to the invention of the PDF, the kindle, and Lulu/Createspace (that is to say, the rise of self-publishing in general).
I've also had several Forgists or Storygamers, in arguments with me, claim I'm "not a game designer" because the OSR is just imitative and not "real design", since I don't use jenga blocks or whatever.
And I've spoken to several publishers of small press games who expressed their frustration at the way that the "indie game" crowd created a little coterie that shut out anyone who made games from an ideology that they didn't like (i.e. regular RPGs, rather than storygames). If you're one of these, and brave enough to say so, and to comment about how you were shut out, I'd sure like to hear it - I know you're out there, because you've said it to me before, but I don't want to be the one to out you.http://therpgpundit.blogspot.com/2015/05/the-real-legacies-of-forge.html
