The specific claim is that there is evidence that wotc products are aimed at
younger audiences:
Per your claim of "soft, sleek, and silly," I would question whether that's specifically for younger audiences or just a wider variety of audiences at all ages. And second, along those lines, the tone of their products seem to vary which doesn't suggest a trend, and they are revisiting heritage settings which is a gamble because new players may or may not actually care about those settings.
Are the following books "soft, sleek, and silly"?
- Call of the Netherdeep
- Van Richten's Guide to Ravenloft
- Fizban's Treasury of Dragons
note, I'm not asking whether you like critical role or not, or whether you agree with any lore changes in VRGtR. How would you characterize these books in terms of their
tone?
