Civilization Revolution (full title: Sid Meier's Civilization Revolution) is a 2008 iteration of Civilization developed by Firaxis with Sid Meier as designer for the Nintendo DS, PlayStation 3 and Xbox 360 consoles. 

Sid Meier was enthusiastic about this installment, being quoted in both the press release and trailer as saying, "This is the game I've always wanted to make."

Civilization Revolution is a turn based strategy game. In past installments the player had more control over the rules of the game and often the game could last for more than ten hours. In Civilization Revolution the games for the most part can be finished within three hours. For the console version, the gameplay has been streamlined and simplified to make the game easier to play for newcomers to the series.

In addition to naming cities, players are randomly allowed to name a geographical feature such as a mountain range, plains, or rivers.

A victory can be achieved in four different ways. Unless specified/defined in a scenario all four victory conditions are open to be used. Different civilizations have distinct advantages over others depending on their "bonuses".

• Domination: One must capture all other civilizations' capital cities, but they do not need to destroy/capture every city.
• Culture: Obtain a total of 20 great persons, wonders, and/or converted cities in any combination, and build the United Nations wonder.
• Economic: Acquire 20,000 gold and build the World Bank wonder.
• Technological: Be the first to reach Alpha Centauri.

If the player's civilization is nearing one of the above mentioned victory conditions, all other civilizations will declare war on them in an attempt to delay or stop them from winning. The construction of the World Bank, the construction of the United Nations, and the launching of the ship to Alpha Centauri can all be stopped by capturing the enemy's capital/palace.

Universe at War: Earth Assault, begins in the year 2012 when an alien race known as the Hierarchy lands on Earth to strip-mine the planet. Before their landing, observatories and scientists on Earth gave warning of aliens but the human race, as a whole, is not able to organize a unified military front against the alien forces. Because the Hierarchy has vast military experience from invading and destroying other planets in the universe, the human race is not able to withstand their forces.

When the Novus arrive on Earth, they expect humanity to be extinct and earth's surface strip-mined, in accordance with Hierarchy standard operating procedure. However, the Novus find Earth mostly intact and the human military not yet entirely wiped out. Humanity owes its continued survival to the fact that Kamal Re'x the Abductor, the overseer in charge of the Hierarchy's Earth invasion, has held back the bulk of his forces to lure the Novus into a trap. Kamal Re'x hopes to earn a promotion by wiping out the Novus expeditionary force. When the Novus arrive, Hierarchy forces are still fighting, and the Novus hope to achieve victory by engaging the vastly superior numbers of the Hierarchy in small groups. In the end, Novus proves unable to stop the Hierarchy, suffering a major defeat when the command base on Earth is destroyed, along with the portal then intended to use to return to their planet, and their leader the Founder. Khamal feels that he's beaten Novus and orders the the Hierarchy super weapon, The Purifier, which can destroy large areas of the planet in one blast, to be prepared to destroy the Earth.... etc
