Hats off to anyone that enjoys D&D and gaming. It’s a passion of mine and has been since childhood. Lots of room for lots of flavors. That said:
This picture is one of many from several books that seems odd as a D&D exemplar. Many examples going back to Tasha’s. The objection I have to the tone is not about one picture in one adventure. That is an absurdity.
Secondly, there can be many flavors of D&D in different campaigns and supplements. I don’t argue against Eberron any more than I do the barrier peaks. That said, the game needs some kind of baseline somehow some way. Eberron and the barrier peaks are novel and cool because it’s not D&D as usual.
“You just don’t like different cultures.” What? You don’t hear me complaining about ancient Asian or African warriors wizards or priests in the game. It’s not “only” about medieval Northern Europe! though that is part of the roots of the game and should not be excised. Too many cool myths and images.
The game is about, at its core, swords, axes spears and a struggle against things that scare us. Why? Tradition surely, but the game is about myth! Our myths don’t usually masquerade as as science fiction (oh wait Star Wars

and when it does funny that light is in ‘saber’ form.
Perseus, King Arthur, Samurai, vikings…hell “cave people.” They fight with magic or weapons against ancient terrors embedded in our shared cross cultural history and archetypes.
If you get the same vibe from LtCol Smith landing his chopper and heading to a disco I don’t dislike you. It’s just not what I am looking for as an archetype or promotion for D&D.
And while tastes change and these crazy kids like some trippy stuff…(and D&D in stranger things is likely to resonate less with some of them less than those who grew up on D&D), even my kids are hip to swords and torches and the trappings of fantasy without prompting. Was it Elden ring or Lord of the Rings that prompted them? Yes.
I do NOT think the game suddenly lost all grounding. But the art direction is swerving away from a coherent baseline more than I would like. If you think otherwise I accept your freedom of choice but not the drift in tone for my game. It’s ok to say that, think that and own it without meaning more insidious things or wishing unhappiness on those who like smiling, bespectacled pigeon
toed colorful protagonists. I don’t prefer it personally and don’t want to buy books replete with that kind of imagery.
Others can and will and world will turn. But I think it’s less cool for it.
