Just finished working my way through the first Black Powder supplement The Last Argument of Kings.
Pete Brown has done a lovely job with this supplement covering the main conflicts of the 18th Century, in Europe and the colonies. After a general introduction each section gives an overview of the conflict, some detail on the armies together with army lists and special rules. Finally a battle scenario together with an ORBAT.
And of course no rule set would be complete today without eye candy. This supplement has it in buckets. I know some gamers criticise this trend, but I simply don't agree. Well painted and displayed wargame figures should inspire the reader. Several members at my club are looking to try new periods based on this.
I am planning to use two sections as soon as possible. Storm on the Danube covers the Ottoman conflicts with the Austrians. I also plan to dust down my Mughals for Plassey and other battles in India.
