National Spirits: Decide what your Nation is famous for by selecting National Spirits and using the bonuses they provide to customize your nation to better achieve your goals. Combine multiple National Spirits as you progress through history to craft a unique civilization in every game.

Develop a Strong Society: Invest in six different Domains that influence the focus of your Nation – Exploration, Government, Warfare, Diplomacy, Engineering, and Arts.  The better you provide for each, the more your Nation can make use of unique Domain Powers. Everything from claiming territory, to adopting new governments, to spreading religion, to reinforcing Armies flows from mastery of the Domains.   

Deep Economy: Design an economic supply chain to support your strategy.  Gather raw materials, then build Improvements to refine basic Goods like logs or iron into lumber, paper, books, ingots, tools, or weapons – specialized products that allow you to improve and adjust your economic engine to suit whatever history sends your way.   

Combined Arms Warfare: Customize your approach to war by combining individual Units into powerful Armies.  Each Unit influences the capabilities of its Army, allowing you to employ a vast number of varied strategies.  Once in conflict, watch the action unfold through the Combat Viewer, where battles play out and provide details on how different Armies perform.
