And yes, consigning Greyhawk to the trash can of history is quite possibly the best commercial approach, no argument there.
You see, that's where I disagree. I think that there is a benefit to the younger fans. But there is also a massive benefit to Hasbro.
When you think of D&D as a
brand, then the reason for reviving Greyhawk should become obvious. At least, it is to me in terms of the IP.
Look at two of the most recent books; yes, Mordenkainen and Tasha (Iggwilv) can span the planes, but both of them have their historical roots in Greyhawk- one of them as Gygax's PC.
Some of the most notable people and personages came from Greyhawk, no matter how much other settings have appropriated them.
Vecna.
Kas.
Acererak.
Iuz.
Keraptis.
It's hard to even understand some "generic" lore, such as the story of Grazzt, without understanding Greyhawk (Iuz, Iggwilv, Eclavdra).
If you're looking for Bigby's hand spells- that's Greyhawk.
If you want to know about handy haversacks or everfull purses- that's Greyhawk.
If you need a tiny hut? That's Greyhawk.
If you're looking for the silly names that you may not even realize are silly (Melf, Drawmij, Rary, Tenser, Otiluke) - that's Greyhawk.
Want to know about Lum the Mad and his betrayal by his former general? That's Greyhawk.
(Also, what is it about your most trusted lieutenant betraying you in Greyhawk?)
You get the idea. There is so much PURE IP GOODNESS to keep alive and to monetize.
I am not saying that my way is the right way- there are a number of ways to do this. But not doing something with the setting that continues to have tendrils (named tendrils) throughout D&D seems like a wasted opportunity.
I may not be a huge fan of Forgotten Realms, for example, finding it bland, but I also know that there is a ton of lore and Hasbro would be crazy to put it in the trashbin of history because the kids today find Elminster stupid.
