I think regional books refer more to the SCAG, but for regions outside the Swordcoast region, like the Old Empires, the Lands of Intrigue, the Heartlands, The Cold Lands, the Utter East, Kara Tur, Zakhara, the Shining South, Chult (no ToA does not count, it lacks indepth look, and doesn't include Samarach and Thindol, etc...) etc..., it's a huge missed opportunity.
Except SCAG is the worst selling book of 5e if I’m not mistaken?
