Not sure that I agree with
@Ruin Explorer here, though I get where much of your argument comes from, and I’m also aware that part of my thinking may be “wishful thinking” as a D&D player since 1976.
If we are are talking about the 50th Anniversary of the game, this creates its own nostalgia to a pretty powerful level. I just cannot see how any other setting gets close to surfing this wave as Gygax’s original, which also spawned so many of the cultural reference points of the game, from Acererak to Zuggtmoy.
Personally, I’m not a purist and would completely welcome an updated version....in fact, I believe this would be crucial....but I think “zero awareness” of GH is overstating the case in regards to younger fans of the game.
50 years = Greyhawk.
