Thank you.
But why fail at an impossible task, when they can succeed at a useful task...?
Again, they do detail all of the story-related geography: six novels and various web short fiction are almost entirely Tenth Disctrict centric. The Millions of square miles of Megacity are not detailed, and billions of sentient beings not named in the fiction, why expect that here? The important elements are the Guilds and the Guildpact which binds the world.
In between Sky Kings Thunder and Tomb of Annihilation, they published a book that had Against the Giants and Tomb of Horrors to acclaim and financial success. I doubt they are that concerned with repeating a theme from 5+ years earlier (at the time of any potential DL book) as you suspect.
In terms of what they do plan for settings, we do have big clues. The DMsGuild used to have all of the D&D Settings listed, now they have a smaller list that is identical to the shortlist from the recent marketing survey: Ravenloft, Dark Sn, Eberron, Greyhawk, Forgotten Realms, Planescape, Dragonland, "Plane Shift" (M:tG material) and "Search Settings" (Which includes Mystarra, Spelljammer, Nentir Vale and Birthright material).
An argument can be made for all of the named settings they are mentioning on a frequent basis as being a unique genre style (Mearls intermittently tweets about how Greyhawk his favorite setting, has unique genre elements, like he is making a case to somebody).
I doubt it. They have probably been thinking about doing a M:tG crossover officially for a while, given the success of the free booklets. Still plenty of room for Cosmic fantasy as a unique genre, with need for other Races, Subclasses, tables, monsters, etc.
I think Keith Baker has other ideas. I take it as a given that a DM will need to invent more content than supplied, for any setting.
Actually it's more like 1 trilogy of novels, 1 lone novel that isn't billed as a Ravnica novel, but very much is, and a trilogy of novellas. And a bunch of short stories on their website.
I stand corrected, though the point stands: as far as I can tell (not having read the novels, looking around the Magic info out there), 99%+ of the stories are Tenth District centered, and the Tenth District is itself a huge city within a city. Is that correct?
Partly. Yes the 10th district would be like say Toronto surrounded by a planet sized Greater Toronto Area, but the rubble belts would be a mix of Detroit and Flint Michigan.
It goes like this, the Ecumenopolis of Ravnica, City (Capital of Ravnica) is also called Ravnica, and within that huge city is the 10 district and within the tenth district is 6 precincts. So yeah it's big.
But only part of the novels take place in the tenth, it's one of the most important parts, but other districts do get mentions and visited. Utava is a condemned rubble belt area that is owned by the Orzhov with a small town in the centre, it's an important location as well, and in fact Teysa is the Baroness of Utava.
There is also the Ghost District which acts kind of like Ravnica's Shadowfell and Ethereal Plane.
There is Old Ravnica, basically Ravnica's underdark.
The World Soul sort of functions as maybe the Ravnica feywild sort of, maybe, but more spiritual.
Then there are a whole bunch of Zonuts run by the Simic and even a District that is partial submerged.
Even the polar regions get mention which where a lot of the fresh water comes from.
So just doing the 10 District is like justing doing Waterdeep and saying here is the Forgotten Realms, ignoring the existance dozen of cities, nations, cultures, and so on.
Ravnica also has two moons. It will be interesting comparing fan made Ravnica Planeshift articles and Guildmaster's Guide to Ravnica.
The whole place is urban sprawl, much of it abandoned and overgrown, with 10th being the capital and headquarters.
I would have like at least a brief over view the other districts and regions like the Ghost District, Utava, and the Polar Regions and so on. In all Honesty this book to do things really right should have made three separate books, a Ravnica Campaign Setting Guide for world lore, A Ravnica Player's Guide, and a Ravnica Monster & NPC book.
Still GGR will be fun, just like the SCAG and Wayfarer's Guide to Eberron, too anorexic.
Every setting they touched so far, Ravnica, Eberron, Forgotten Realms, Ravenloft has well well done, but only half done or less. It quality, but unfinished to so someone else mentioned, you have rely on Wikipedia and other sources to make up for it. That is shameful. Heck even Dragon Heist needed an outside suppliment.
I just want to remind you all I was right.
I pointed out multiple times, since SCAG and CoS, that the new norm was settings that lightly season the D&D game, not mega-guides that completely re-write the PHB and MM. People were still convinced that the old paradigm born of box sets and branded supplements would return. And now we're four settings in and that has yet to appear.
Ravnica was the Canary in the coal mine. It was a setting bereft of any D&D tropes from races to magic to monsters. In years past, it would have probably been a complete campaign setting, monster supplement, magic supplement, players guide, and an extensive re-write and ban list from the players handbook to capture the MTG feel and lore. But WotC isn't about that life anymore, so the guide instead assumes most, if not all, D&D tropes live alongside the Magic ones, and indeed take precedence over them when it comes to rules, which if why the color pie of MTG appears completely absent despite literally being the basis of the 10 guilds.
So we had Forgotten Realms that just fleshes out the default assumptions without radical departure, Eberron that just reflavors and adds more options to the base game without removing any mechanics, Ravnica that does mostly the same, perhaps changing some race options. Ravenloft, as presented in Curse of Strahd, similarly strips the additional mechanics and laundry list of restrictions to focus on horror-themed D&D. Anyone harboring the belief that a Dark Sun or Dragonlance update will not allow paladins, monks or dragonborn is probably going to be disappointed.
Really though, it's for the best. One of the best products, I've been told, is a folio from 1983 with a lot of blank maps and a whiff of lore. Maybe we should look at this as the new Greyhawk folio?
