This is fantastic news. They also said they will go to court over if WoTC try to “deauthorise” OGL 1.0a which is just epic.
Edit: The site went down lmao. Epic stuff.
Edit: BTW, Paizo is the company that also recognised their Union without requiring it to go to vote or hiring anti-union shitheads.
So from one convoluted reddit post it's the d20 system of the WOTC public SW RPG, that was then swapped for the FFG SW RPG that utilized some form of the OGL for 3rd edition (or at least that's the claim). Of the actual verifiable information is that they do use the D20 system of 3rd edition for all of the background math (feels like this is a dive into early 2000s game design lore and law).
