So, funny story: While 3.5 was the first edition of D&D I played, 4e was where I really got into the game. And when Paizo came out with Pathfinder, selling itself as a way to keep playing 3.5, I thought, “how is that even legal?” So, I looked into it a bit. Found out about this whole OGL vs GSL controversy. And though I’m ashamed to admit it, I came away from that with an anti-OGL perspective at the time. Crazy, I know, but as a fan of 4e, Pathfinder just looked like this refuge for stuck-in-their-ways 3e fans who just hated 4e, and the OGL looked like a well-intentioned document that unintentionally enabled the “grognards” to split the D&D player base. It looked to naïve 17-year-old Charlaquin like the OGL was ultimately to blame for the Edition War.
Of course, now I recognize that the RPG industry is bigger than just D&D and Pathfinder, and that the OGL is an incredible resource for third party publishers that the whole industry benefits from, perhaps D&D most of all. It only hurt 4e because 4e didn’t use it. The GSL was actually the thing hurting 4e. But now, I fear all the folks who started playing with 5e may end up thinking the way I used to about the OGL. It may look to them like it did to me, this weird relic of the past with a loophole that enables competition from bitter old players who can’t get with the times, and that they might celebrate the idea of it being revoked.
My hope though is that these newer players who have enjoyed the benefits of the mass of 3rd party support for 5e will recognize that this wealth of support is owed to the OGL. That would be my angle for trying to convince 5e first-timers to care about this issue. “You like Kobold Press stuff? Deck of Many? All the 3rd party supplements and settings that are always getting Kickstarted? None of that would exist without the OGL 1.0).”
