Complete the tutorial:
Get the Activity Center project from the Projects tab.
Build can be defined as your nation's setup, consisting of city count, infrastructure, land, general improvements and MMR [Minimum Military Requirement].
You should have a single template [city improvements] for all cities, this means that you should not keep different cities with different templates.
3-5 Cities at most.
Keep 750-1000 of Aluminum, Steel, Gasoline and Munitions PER CITY.
500 Uranium and 20,000 Food.
This will be your 'Warchest'.
1000 Infrastructure
1000 Land
Use the following template, copy it then apply it here.
