I started a campaign with my 3 regular players and I as a GM am having a blast.
At first I was a bit worried that the automatic mechanic used for encountering myths omens as the knights travel would make adventuring somewhat passive, but in reality, with just a bit of human drama between holdings, picking unused knights as NPCs to act as the players rivals, and using the weirdness of the seers and their wants, I have a bunch of exciting threads in my Realm on top of the myths. It almost runs itself and between session prep is quick and fun.
Combat is always quick and dynamic, all our fights so far have been close calls and lasted exactly 3 rounds.
The art in the book is gorgeous, I wish we could get some of these pictures separately, they'd make great posters or wallpapers.
