If you haven't heard, Gary Gygax's Yggsburgh sandbox campaign setting, originally released in 2005 and withdrawn from sales after he passed away in 2008, is once again available for purchase from Troll Lord Games, following an agreement with the Gygax estate. You can pre-order the hardcover from the TLG site for $65, which also includes an immediate download of the PDF, or you can buy the PDF alone from DrivethruRPG for $19.99:

For those unfamiliar with it, Yggsburgh is a re-casting of Gygax's long-delayed City of Greyhawk project, intended as a setting for exploring the Castle Greyhawk dungeons, here re-christened Castle Zagyg.  

Back in May of 1980, shortly before the initial publication of the World of Greyhawk campaign setting, Gary Gygax discussed future releases for the setting in issue 37 of The Dragon, where in his regular column "From the Sorcerer's Scroll", under the title "Greyhawk: The Shape of the World", he estimated that "The City of Greyhawk might make a 1981 publication date, certainly 1982, and about the same time the series which will eventually represent the whole of the Dungeons of Castle Greyhawk will begin". Sadly, neither title ever appeared under Gygax's byline, and became the most infamous of TSR vaporware. 

Decades later, in the early 2000s, Gygax finally started a new project to publish this material, this time under the aegis of TLG's Castles & Crusades RPG. However, only Yggsburgh and the first portion of the Castle Zagyg, titled the Upper Works (2007), were finished and released before Gygax passed away, and the license to publish them was withdrawn.

Yggsburgh is a sprawling 256-page hardcover book, with cover art by the great Jeffrey Catherine Jones, repurposed from the 1972 Avon paperback edition of Nine Princes of Amber by Roger Zelazny. This was the first novel in the Amber series, which was included by Gygax in Appendix N in the AD&D Dungeon Masters Guide in 1979. Originally, the entire series of Castle Zagyg books was slated to feature covers with Jones' classic work from the 1970s.

The book itself is also accompanied by an 8-page hexmap, drafted by Darlene in a style similar to her original maps for the World of Greyhawk, which was tipped into the back cover in the 2005 publication. This depicts an area 50 hexes east-west and 34 hexes north-south, at 1 mile per hex, for a total area of 1,700 square miles:

Rather than just being a high-level gazetteer, Yggsburgh is a big sandbox, which I'd compare to Lenard Lakofka's AD&D module L1 The Secret of Bone Hill. There's a city with 93 described areas, including the famous Green Dragon Inn, and an area map with 48 described locations, and including a number of fully detailed small dungeons, which is often overlooked: 

• Thieves' Underground (13 rooms)
• River King's Tomb (19 rooms)
• The Cursed Mine (14 rooms)
• The Gnome Burrows (25 rooms)
• The Unholy Ringstones (25 encounter areas)

These could easily be extracted and run as one-shots or dropped in other settings. 

Castle Zagyg and Rob Kuntz's Dark Chateau (2005) are also two of the intended locations in the sandbox, so there is the potential for larger dungeons, although this does make the campaign setting incomplete on its own if you intend to use those.

I've had the original hardback for many years, and it's probably my favorite late-era Gygax product. While I haven't run anything from it yet, I will pick it up every now and then and read a bit. It's sort of a glorious sprawling mess like the original AD&D DMG, but in campaign setting form.
