Interesting take on mass battles… I really like the Victory Points System, the handling of surviving units on the losing side, and how they assign VP's to regions of the battlefield. Those can easily transfer to 1st/2nd Ed. BS games, wholesale.
The idea of tracking HP for each Stand, however, will really slow down the combat resolution. You will only remove a figure when that "Stand" reaches zero HP, plus the bookkeeping for each Stand/figure…
There are only two classes of Morale: Good, and Broken/routing. That is a killer for me, as it means you are either perfect, ready to fight, or running for your lives!
Still, all things considered, it is actually a pretty good method for adapting mass battles to an RPG. It could be adapted to any RPG rules system, with little modification, IMO. The price is fantastic -- FREE! Thanks for sharing -- downloaded, read, saved, and shared even, with other mini's/fantasy RPG gamer friends. Cheers!
