Stardock now offers online sales of The Conquest of Britannia the first "micro-expansion" pack for Imperium Romanum, Kalypso's city-building game (thanks Gamer's Hell). Word is:

The Conquest of Britannia expansion includes four new scenarios that will take players across Britannia to found new cities for the glory of Rome. New task tablets will provide even more bonuses, surprises and goals, while gamers fight off barbarian hordes and more. The micro-expansion also includes improved art and game design from the original Imperium Romanum.
