\section{Open Game License (OGL)}

The Open Game License (OGL), is the license which Dungeons \& Dragons 
(D\&D) from 3rd edition onwards (sort of), has been licensed under.  

Initially released in 2000, for content which uses the System Reference 
Document (SRD), as the basis of content to be played with other D\&D 
content.

In June 2008, Wizards of the Coast (WotC), release D\&D 4th Edition, under 
the Game System License (GSL), which is incompatible with the OGL, but it
remained in use.

In January 2016, WotC, released D\&D 5th Edition, returning to the OGL.

Between August 2022, and January 2023, there was debate as to whether the
previous (OGL1.0a) version would be allowed to be used, as WotC engaged in
various releases/reporting suggesting they would be disallowing it, and
possibly even retroactively relicensing content under it to a new license.

In response to this, Paizo created the Open RPG Creative License (ORC), to
help prevent any company (including themselves or derivatives of 
themselves), making decisions such as this.  

Some versions of RuneQuest have been licensed under OGL, and current 
versions are licensed under ORC.
