Napoleonic Era is a renowned, fan-made modification for Age of Empires 3 and its expansions The Warchiefs and The Asian Dynasties. The mod intends to accurately illustrate the time from 1555-1815 by greatly expanding and reworking the game with new units, buildings, maps, sounds, music and civilizations. The mod has been founded in January 2006 by Alexander Fleger and is being continued by Peter Piepenburg since February 2010. It is still one of the most anticipated mods for Age of Empires III in the whole world.
Egyptian Cairo Janissaries are mercenaries who can be hired on West Asian and North African maps.
This reminds me...maybe im thinking overly complex or too much focus, but Poland-Lithuania in the late 1700s had Janissary style troops as part of the Crown forces. Like a royal guard
Maybe they could be a powerful shipment. I'd say make them have redcoats always, but jannisary hat in team colour
They already are Church tech units for Polish. Tech is called "Sobieski's Janissaries". ;)
