I have always enjoyed this original campaign setting. The two authors have spent a lot of time and effort to not only make it a 'fun game' but to also incorporate a lot of historical material. Yes, it is still a fantasy game; but I think anyone who enjoys history, especially of the medieval era will enjoy this setting.
Having used this product in the game I am playing in; I can honestly say good job to the Alea Publishing Group and it's authors, Cameron and Josh. I agree that while not all the powers mesh 100% with each other or a real game, it's a well written and useful multiclass.
