Is that your take? I see recent D&D books actually discuss bad-wrong-fun. There is a whole callout in Van Richten's Guide to Ravenloft telling people to stop playing games a certain way and to stop being inspired by genre tropes.So it's bad-wrong-fun to have monsters? Do vampires need to sparkle in the sun? Is being a werewolf just a power-up? Is someone who loosely bases their imagery on LOTR doing it wrong?
Hence, I expect 50th Anniversary Editions of Dungeon and Dragons will either ignore that modern trend and return to the design philosophy of Gary Gygax, or more probably, just reinforce the bad-wrong-fun callouts and distance modern designs further from the Gary Gygax vision. The future of D&D rests on that 50th Anniversary.
