D&D drowns out the rest of the market, practically speaking. We don’t have a great way to measure overall play but Roll20, the dominant virtual tabletop, publishes their stats regularly and D&D is more than 50%. Call of Cthulhu is around 15%. It drops quickly from there. There’s a huge network effect at work here. It’s easier to find D&D players than players of any other game — not that you can’t find them, but D&D is easier. WotC runs organized play programs such that I can walk into almost any brick and mortar tabletop gaming store in the country and immediately find a regular game. Look at https://startplaying.games/search https://startplaying.games/search and count the number of D&D games compared to anything else. And this has happened before. D&D 4e got rid of the OGL, which made people have these same conversations. This did create Pathfinder, but even cloning the earlier version of D&D didn’t prevent WotC from dominating except during the year or two between 4e and the current edition. Plus 4e played really differently, which won’t be the case for this new edition.
