I have all the monster books and a bunch of the short adventure books, plus Streets of Zobeck. I don't have the Midgard setting book.
It feels very like Paizo's Golarion ca 2010, before they went mad. Kitchen sink but some particular emphases - Steampunk, Eastern European & Scandinavian fantasia, and desert/Egypt. Those are all in Golarion too. More Fey perhaps; Fey are a big thing. A female Goliath Fighter IMC is (very slowly) falling for a Shadowfey Guardian NPC they fled the Carrion Shrine of Qorgeth & Crypt of Green Shadows with.
Compared to WoTC fantasy, it's darker and earthier, but not hopeless/Grimdark. It's good, I like most of it, it definitely freshens up my Forgotten Realms campaign.
