# Although Germany during AoE3's time period was simply a bunch of small nations, the strongest nation, Prussia, was a strong European power throughout the 18th and 19th centuries. Although the Prussians didn't get involved in colonization, the fact alone that they represent all Germans nations in AoE3 shows that they weren't included to be realistic. Many Hessians, a German faction, were hired by the British to fight for them during the American Revolution.
# Bonus: With every shipment the Germans receive past the Discovery Age, they get free Uhlan cavalry, 1 for every Age they advanced (2 for Colonial, 3 for Fortress, 4 for Industrial). They also have the option of shipping over a Settler Wagon, a powerful and productive villager. It's also much easier to hire Mercenaries.
# Unique Units: Doppelsoldner (heavy melee infantry), Settler Wagon (unique settler), Uhlan (heavy cavalry), War Wagon (heavy ranged cavalry)
# Royal Guard: Needle Gunner (Skirmisher)
