I don't care how many people buy that pos, my point was that D&D keeps changing rulesets. 2e, 3e, 4e, 5e, 5.5e, and now a possible 6e, which all require the playerbase to buy new books for each edition, this is not a firm foundation. D&D's fanbase are loyal to the D&D brand, not the game mechanics (the players that were loyal to 3e game mechanics went to Pathfinder, the ones that were loyal to 2e went to OSR games). Therefore any game trying to appeal to D&D players will have to engage in this constant creation of new D&D-compatible editions to keep appealing to them.
They made their choices. *shrug* Propaganda does not good art make.
D&D's new romantasy genre is doing well, though.
EDIT: Call of Cthulhu and Runequest both have more editions than D&D, but the game systems in these editions are still very similar and to a large part compatible. D&D's new editions are often completely different games with the same name and similar setting fluff, like 2e to 3e, 3.5e to 4e, 4e to 5e, and now 5.5e to the possible 6e.
EDIT: And Stranger Things is done now, and Critical Role moved on from D&D, so it won't have those to help it. Who cares, time will tell.
