Paizo (publishers of Pathfinder) react to rumors of Wizards of the Coast moving from the existing Open Game License to a new, predatory license and attempting to somehow retroactively revoke the old license: https://paizo.com/community/blog

The punchline: Paizo previously used the OGL to release their original content because it was there; now they feel it is no longer trustworthy so they're making their own license.

The name: The Open RPG Creative License (ORC).

Sorry, I think I may have been unclear here— the ORCs are the good guys

If you haven't been following this: Around 2000 D&D 3e was released using OGL 1.0a, which Wizards created. After 23 years gobs of commercial work has been released depending on this license. About a week ago Wizards started privately sending creators a "OGL 1.1" with alarming terms. Originally it had a go-live date of *TODAY*. The new license immediately leaked, and there was uproar.

Today Wizards announced a livestream to discuss the controversy. Then cancelled it.

Wizards of the Coast Cancels OGL Announcement After Online Ire

The new Dungeons & Dragons Open Game License was expected on Thursday afternoon, but a fan campaign against changes has caused the company to hesitate.

Gizmodo

Follow-up: So one week after canceling the launch of "OGL 1.1" aka "OGL 2.0", Wizards has launched "OGL 1.2". They brag they've addressed community concerns in various ways, but I don't think they have. For example they brag the new license contains the word "irrevocable" (although they define it to mean something special in the document so maybe it's still revocable). But the outrage was that Hasbro was trying to revoke the *old* OGL, 1.0a. And they're still doing that:

D&D will move to Creative Commons license, requests feedback on new OGL

A new draft of the Dungeons & Dragons Open Gaming License (OGL) places the core rules of the seminal tabletop RPG in the Creative Commons. “We’re giving the core D&D mechanics to the community,” said the executive producer. Feedback is due by Feb. 3.

Like I don't th… I still don't think they can do that. "Deauthorize" a license they licensed content to you under previously as they purport to in that screenshot. Unless this is some kinda "by using OGL 1.2, you agree to stop using 1.0a" thing, everything I know of US contract law is if you let people go 23 years understanding "if I'm holding a copy of the book with the license in it, I have the license" you can't just say "okay backsies, the license printed on that paper isn't real anymore".
I am not a lawyer
@mcc Nor am I; just reading the news on this. From EFF's post (https://www.eff.org/deeplinks/2023/01/beware-gifts-dragons-how-dds-open-gaming-license-may-have-become-trap-creators), it sounds like they very much can do a backsies on this. In his video, LegalEagle did make the interesting point, though, that if they did, then Wizards might be subject to a promissory estoppel (https://www.law.cornell.edu/wex/promissory_estoppel) by third-party publishers who reasonably relied on OGL 1.0x being irrevocable.
Beware the Gifts of Dragons: How D&D’s Open Gaming License May Have Become a Trap for Creators

The company that owns Dungeons and Dragons (D&D) is planning to revoke the open license that has, since the year 2000, applied to a wide range of unofficial, commercial products that build on the mechanics of the game.

@cgranade That second thing is what I was thinking when I mentioned contract law, yeah. If someone undertakes a business activity understanding a read of a legal document, and you don't stop them, then that can create an implicit contract sometimes, & you can't go back and say "well, I always understood the contract differently". This is worse for Hasbro bc the ex-employee original license grantors will come back and testify Hasbro's new interpretation is NOT how they understood it at the time.
@mcc Right, agreed. What makes that complicated is that someone would have to have already relied on that promise for estoppel to apply, I think? So new or smaller indie third-party publishers can't use 1.0a going forward? Maybe?
