to achieve a Domination Victory, since half the vassal's land and population count towards a domination victory for the master, but not vice versa. Similarly, if the master goes to war with another civilization, the vassal too has to go to war. However, other countries' opinions of you will worsen if you have a vassal they dislike. The vassal may still reject trades for gold and technologies. During peacetime, civilizations can offer their vassalage in return for protection from an enemy, but it may be ended if the state's relative land and population statistics change. Vassal agreements signed in a state of mutual war, as part of a peace treaty, are considered capitulation and bind both parties. The agreement is terminated, however, if the vassal acquires 50% more land area than the master or the vassal loses half of the land it held when the agreement was signed. The only way a master can terminate the agreement is if the vassal refuses to pay tribute. The master can then choose to declare war. In order to make the civilizations more distinctive, every civilization has received a "Unique Building". These unique buildings replace the standard buildings, and grant special advantages. New civilizations include Carthage, the Celts, Korea, the Ottoman Empire, the Vikings, and the Zulu. Four new leaders are introduced for existing civilizations. Three new leader traits are introduced, and many existing leader traits have been changed. Warlords includes new music and also features older music directly from Civilization III and Civilization III: Conquests, which augment the game's existing ancient and classical era music that had relatively few selections. The new opening theme is a Lebanese love song entitled "Al Nadda". Reception The expansion received generally positive reviews.
