Vanilla

 * The editor is much simplier: much of the map designing will be similiar to the Rise of Nations scenario map editor.
 * Now, for the first time in a real time strategy game, there will be Great People, divided in Great Prophets (who increase the morale/happiness and production in the province, and found a new religion for the player who discovers the religion's correlate technology first (for example, )), Great Merchants (who can explore a rival territory untouched and perform trade missions, which can improve relations between the two players), Great Scientists (who can build the Academy, which doubles the Tech Points production from all Universities/Laboratories and Temples), Great Artists (who can build a Great Work, which increases the Culture in any province by 4000) and Great Engineers (who can instantly build any World Wonder or National Wonder)
 * Gorvernment is now divided in 5 categories: Government Civics, Legal Civics, Labor Civics, Economy Civics and Religion Civics, which offer various advantages. Each category can accept JUST ONE of their Civics.
 * Diplomacy is much more transparent: not only the players will know what do the others think about them; they will also them in what way, via reputation points added or subtracted thanks to good or bad actions towards the other leaders.
 * If more than one player is building the same World Wonder, the first who completes its Wonder wins; the others will have to get double the original cost of the Wonder and start a new project.
 * Finally, there's a new way to win: a Diplomatic Victory. Building the United Nations will double the votes on the player who build them, whatever the resolution is, including Diplomatic Victory.

Added in The Art of Domination

 * A new Great Person has been added: the Great General can battle alone as a standalone unit (just like the Military, Economic and Imperial Leaders from Empire Earth II and the Warrior and Strategist Heroes from the first Empire Earth).
 * The World Conquest mode allows to play as many factions in game during some of the most important periods in human history, or even play as an empire and guide it to glory from 500'000 BC to 3000 AD.
 * Thanks to the Apostolic Palace, it's now possible to archieve a Diplomatic Victory much earlier in game.
 * Native tribes are now back. There are Visigoths, Ostrogoths, Ainu, Maori, Inuit, Vandals and Huns, and often offer mercenaries.
