WotC benefits a lot from the OGL, but not in a way that shows up in a financial statement. They benefit by having smaller and more agile 3PPs, with lower overheads and lower demands on profit margins, create niche support material that wouldn't be profitable enough for Wizards to make. They benefit by having 3PPs provide D&D-adjacent alternatives for people who want to branch out into non-D&D games – a group who tries out a 5e-based sci-fi game is more likely to keep buying 5e stuff and maybe play 5e for the campaign after that than a group that tries out Star Wars or Infinity. And at least Dancey has suggested that even Pathfinder was a long-term benefit for Wizards, because it kept players disaffected by 4e in D&D's orbit, ready to be picked up by 5e instead of quitting RPGs altogether or moving to entirely different games.A better word for this is Symbiotic. The key is ‘mutual’ benefit. We can see how 3pp benefit from D&D marketing, growth and brand recognition. Not so clear the extent to which WotC benefit.
3PPs probably benefit more from the OGL than Wizards does, but Wizards clearly benefits.
This is a keen insight, but it kind of boils down to slavery being a very prominent part of the Dark Sun setting, and at the same time something of a "third rail" in contemporary gaming discourse. And this in turn leads into something I've been noodling over that I call the Wakanda vs Luke Cage fantasies (in short: in the face of real-life oppression, both the Wakanda-style vision of a better world where that problem doesn't exist, and the Luke Cage vision of a world where oppression still exists but I'm the one who can do something about it, are ways to tell great stories). Dark Sun is a great place to tell Luke Cage stories, but it sure as heck ain't Wakanda.People who "like the idea" are. And the concept of Dark Sun? It literally gets more relevant every year lol (unfortunately). The two biggest themes - "environmental destruction" and "individual greed and the hoarding/centralization of wealth/power" are absolutely 150% 2020s themes, way more than in the 1990s! Add in the "ultrawealthy transhumanist" angles and you're probably talking a 2030s-relevant setting lol.
