Germans Love David Hasselhoff: Between one third and fourty per cent of the first game's global sales were realized in France alone in the 2000s. Likely as a result of this, the sequel focused on The Napoleonic Wars, with Emperor Napoléon Bonaparte's portrait and the French flag on the cover to boot.
Protagonist Title Fallacy: The games do have Cossack units and there are campaigns centered on the 17th century Cossack Hetmanate in Ukraine in European Wars and The Art of War, but the other campaigns (bar parts of the Russian and Polish ones) are not about Cossacks at all, since it covers conflicts between a lot of other European nations of the 17th century and early 18th century from France and Great Britain to Russia, with also the Ottoman empire.
