And "Avor Ring" has the Barbarian Horse Archer (though no wikipedia page or image of it's Strength and Movement, nor favorite album in high school) and some other CS (sounds like Rangnarak) has the Berserker unit, plus gives bonuses to Ship Wrecks.

Dude, your mods are Deity level kool. Thank you so much, they add so much variability and fun factor. Obviously, everyone loves the ones with extra units and buildings, though there are lots of great ideas and bonuses, and some wicked cool art. If I had one suggestion, it would be to err on the side of OP when it comes to suzerain ability. Things like units and buildings fit this bill, but so too would Great People, Envoys, Governor Title, a Spy, etc. Something that makes you really salivate and want to invest the Envoy capital to make it happen. Or keep fighting for. Entiendes, amigo?

Muchas gracias por todos, Gedemo.

Thanks for the clarification.

the suzerain can now build eagle warriors too.
(I've already made several city-states like this: Vijayanagara with the Indian Varu, Avaris with the Egytian Maryannu, Ordu Baliq with the Mongol Keshig, Zerzura with the Arabian Mameluk)

Hold on, does this mean that any suzerain of this city-state can now build Eagle Warriors or does that perk only apply to the Aztecs themselves? Just wondering.

Nice
