I think it might be good to start adding in 2nd UU's. What I am aiming for here is to have the Western civs have a unit that replaces the Horse Archer so that they don't recruit horse archers and have eastern civs have a unit which replaces the knight so they don't recruit western knights. Byzantium=Kataphraktoi (Knight) Turks=Qapikulu (Knight) Armenia=Aspet (Knight) Egypt=Tawashi Cavalry (Knight) Arabs/Abbasids=Abna Infantry (Foot Knight) France=Gendarmes? (Horse Archer) England=Norman Cavalry (Horse Archer) Italians=Neapolitan Barons (Horse Archer) Spanish=Jinetes (Horse Archer) Moors=Bedouin Camel Warriors (Knight) Germans=Imperial (or Gothic) Knights (Horse Archer) Tatars/Mongols=Heavy Horse Archers (Knight) Kievan Rus=Boyars (Knight) Poland=??? (Horse Archer) Hungary=Hungarian Knights (Knight) Crusaders=Turkopoles (Horse Archer) Khazars=Arsiyah (Knight) Feel free to make more suggestions.
