Gaming is fun, and fun is for everyone
So why do people keep asking for GH to be "redone" for 5e? What are they actually asking for? Why do they need to pay again to read the same stories they've already read?
Couple reasons why I'd like a GH 5E book.
1. To collate or "reboot" the setting for an easy starting timepoint for new groups. There have been a handful of threads here of people asking "What GH books do I buy?" or "What time period is the best to use?" or "What is X nation like?" There's a lot of printed GH material, a lot not good. It needs a good "reboot" into something a little more stable, so people have the history but a good year to start, the current political map, the good base stuff.
2. Something tonally different. There hasn't been a lot of setting material printed that gives a more realistic medieval world. The Sword Coast is the base one, but is much more "we always overcome the Saturday morning villain" in tone for 5E. Ravenloft (Curse of Strahd) is good but is wrapped in gothic horror tropes. Eberron and Ravnica are much more magic-tech. None of these are bad, but we've yet to see a setting that goes for a more realistic medieval fantasy tone (of the peasants being peasants, of humans being intolerant, of nations barely trusting each other on the edge of war).
3. The trappings of "Official." The OP has touched on this, but it's honestly so great to see an old setting get dusted off and getting a fresh coat of paint. A new official atlas of Greyhawk to match the quality of the Sword Coast would be great. Art and stats for Iuz the Evil, the Sorceress Iggwilv, and the god Kyuss would be great. Good design and layout, these things are just plain nice.
Anyway, that's my pitch. Not going to expect it before some other settings, but I'll keep my fingers crossed.
