Well, it was the first of the November rush of pre-orders to be charged but the last of the bunch to actually arrive. Unlike the other November pre-orders, expansions for Memoir '44 and Small World, the new Commands & Colors: Napoleonics and Battle Cry, which are all primarily entertainment, Persian Incursion is about as Serious a wargame as one could ask for.
Just perusing the components and starting to read it this product is clearly the most comprehensive treatment of one of today's biggest geopolitical and military issues -- could Israel attack Iran to eliminate its nuclear program? It addresses the technical and tactical aspects of a potential strike in excruciating detail (using the Harpoon 4 game engine) and the "game" portion (it's a standalone game, NOT a Harpoon module) provides a framework for examining the potential political and diplomatic consequences.
This is going to take a couple of days to digest, but I expect to say more about it later.
