The Aztecs are again led by Montezuma, whose warrior unit can convert defeated enemies into builder units that have the unique ability to speed the construction of districts. Also, their unique luxuries can provide extra amenities and increase the fighting power of their units.
China gets builder units that can speed up the construction of ancient and classical era wonders, and they get extra progress from Eureka boosts.
