Medieval II: Total War Game Info - Diplomacy
As in the original Medieval Total War, diplomacy will be dramatically different from diplomacy from Rome: Total War. The original game featured diplomacy using emissaries and princesses to achieve political gain. The diplomacy system in Medieval 2 has been improved to give the player a lot more information about how the AI player feels both about them, and about the offer on the table.
Also, the player may be able to send an unmarried princess of marriageable age to appeal to form an alliance between two nations through a dynastic marriage. Assassination is also an option for eliminating troublesome opponents (or disloyal generals). As in Rome: Total War's expansion, Barbarian Invasion, the player may also be able to send priests of their nation's religion to create a foundation for later conquest through first converting its people in any given province or to stir up religious unrest among another nation's people. The original Medieval had priests, bishops, cardinals, inquisitors, imams and alims that the different religions could use to spread the faith, improve loyalty, or root out heretics. Medieval II: Total War will most likely incorporate many of these aspects to allow the creation of an empire not only through military conquest, but through skillful diplomacy involving religion, marriage, or assassination.
