Morkus from Orkus
Not exactly. They were region books that provided more setting content than 5e adventures and didn't have wasted adventure space that I wouldn't use. I wasn't paying for a book that I wouldn't be using 80-90% of.Looking back to 1E or 2E, most of the Forgotten Realms support was in region books, which provided similar coverage to what Descent to Avernus or Icewind Dale provide now. FR has one general book, and 7 meaty regional supplements (Princes of the Apocalypse, Out of the Abyss, Storm King's Thunder, Tomb of Annihilation, Waterdeep, Baldur's Gate, and Icewind Dale). Those 7 books each provide a heavy dosage of Setting material, each enough to fuel years of play.
