Variant to priority building is to make 1 or 2 cities upgrade the blacksmith/armorer route, but not the troop buidlings , that way you can moove your troops there and upgrade them .

Similarly you can do this for the appropriate temples.


So I aim for for ( @15 cities)

max population centers 10 , 5 feeding cities(large unit size train peasants and send them off to max pop centers)


1-3 infantry bases
1-2 cavalry
1-2 missile

1-2 blacksmith/armourer specialist cities
1-2 temples specialist cities.

rest of max pop centers to make money, feeder cities also.
