While the south in Midgard is not a region that really excites me... I tend to prefer more Eurocentric areas...... This is an excellent book.
This PG oozes with flavor and options, especially for scaled PCs, no matter where they are from. Your Kobold from Zobeck... or your Drake from the Northlands can still use them.
Also, any amount of new setting information is exciting, and the new bits about the Dragon Empire are a fun read. The Midgard folks have hit their stride, and every new bit makes the world even better.
