GamePro (April 2010) has a great preview of Civ. A few things they mention: Leaders/Civs - (Germany) German leader: Otto von Bismark - (China) China leader: Wu Zeitein/Zetein (two spellings in the article; SHOULD be Wu Zetian) (Mao and other previous Chinese leaders are out) - (America) American leader: Washington (Lincoln and FDR are out) - (Japan) Japanese leader: Oba Nobunaga (Tokugawa is out) - (Arabia) Arabian leader: Harun al-Rashid (Xerxes and Saladin are out) - Other confirmed leaders mentioned in the article (Genghis Khan, Washington, Caesar, Napolean, Gandhi) Looks like one leader per civ a la Civilization Revolution? City-states - City-states: Can provide gifts of gold, bonuses; only one city but borders can grow. Confirmed is Singapore. Terrain - Hills provide defensive and line-of-site advantages - Attacks over rivers are affected - Wounded units can hide in trees and recover Units - Basic military units move two tiles in combat instead of one.
