No. Zunghar Khanate (end at 1756)
Khanate of Bukhara was from 1500 - 1785 too..
So at least there's a successive "dynasties" from the Scythian era to 1785AD..
Well..
I heard that Poland will be added as minor city on 1.9
Kievan Rus = Russia that spawn on Kiev (not Moskva), easy

Greater Zimbabwe = I think I saw this city on Barbs.py but forget when it spawn..
Nubia = Ethiopia? Kingdom of Axum? Though they need to represent the Punt, Makurios too..
I think it's alright for Persia to conquer these area as historically, they are part of Greater Iran.. Zoroastrianism even came from there.. and yet Samanid Dynasty of Persia is based there~
Some of these cities sent tributaries to China on BC years but I forget the approximate~
I think what differ Scythians and this steppe empires most, is that they are not a city builder..they don't settle, built cities, then prosper and wealthy.. but they are a merchant city states, birthplace of many great civilizations, which is guarded by fierce bowmen and horsemen all around
