Really brilliant mod, but could a future version expand on the Eastern Part of the world. It always felt least touched out of all parts of the mod.
Suggestions:
* More units/amazon units for Armenia and Parthia. Maybe some of the eastern Diadochi, but chiefly those two. For example, differentiating Eastern infantry/hillmen. Nakharars (nobles) and Azats (knights) for Armenians. You could have the Azat a cataphract on an unarmoured horse whilst the Nakharar has full cataphract armour. etc
* A bit of a biggy, but perhaps use the mundus magnus/EB map that goes into India with the textures already there. It seems to represent the classical world much better and takes the focus away from Rome. You could then expand the Valkyrie into Central Asia (Kazachstan region) to keep the Amazons involved, they would thus replace the Saka Rauka historically; who conquered India.
* Or, you could remove the Independent Celts (who you can't play as anyway) and put another Amazon faction in India. I vaguely recall in Alexander Total war their being Amazon units that were a reference to a story of him sleeping with one on his conquests. So there is enough justification. You could say that Amazons sailed via the Red Sea to India, established trading colonies and took over; before mingling with the local population.
