Expansion features

• New diplomatic options: let the world know what you think of your neighbours by setting a public attitude to foreign powers.
• Tell the world what you want: designate neighbouring provinces as "places of interest", build trust with other nations, and entice allies with the promise of land for their support.
• Tengri: Tengrism is now asyncretic faith , allowing it to tolerate certain secondary religions as if it were a national faith.
• Horde unity and razing: nomadic nations now must pay attention to the horde unity of their tribes – a unity that can only be maintained by the occasional pillaging.
• Improved culture changes: you can now restore a previous culture to a converted province, or convert a province you hold to a culture that is not your own.
• Native policies: set your policy for colonial encounters with natives. Are you focused on quick subjugation, peaceful growth or trading advantages?
• Improved espionage: new spy actions allow you to study the technology of more advanced countries and prod your rivals' subjects towards independence.
