EALA (makers of Command and Conquer: Generals) have just annouced the first expansion pack for the game entitled: Command and Conquer Generals: Zero Hour.
"Players will wage a global war to become the ultimate General of modern warfare as they square off against the world"s most elite commanders. An all-new Generals Challenge mode will allow players to control any of 9 distinctive armies in battle through 9 computer-controlled Generals. After defeating the AI Generals, players will have the ability to select conquered armies to play online."
Could this be another Sims with expansion pack after expansion pack? Only time will tell.
