Update 25 Jan 2019: a nice review already from Dave Watson, better known as "Balkan Wargamer" and an expert on the Balkans and its many conflicts down the ages, who rates BBBB as "highly recommended"!
Also a nice positive review (I'm told) in Turkish from Kahramangiller.
An included overview of the historical events and biographies of many of the commanders whose roles you reprise on the table-top will provide you with the background to give you an inkling of the vast stakes and human drama associated with these battles. An annotated bibliography provides you both with the sources used to build the scenarios and further reading to enrich your understanding and experience. A figure guide helps you find suitable ways to represent the armies in almost all scales of miniature war-gaming.
A struggle for a vast future awaits! Take command and see how history was forged!
