From the announcement:
WizKids is thrilled to announce the upcoming card game, Time Barons, designed by Jon Perry and Derek Yu. In Time Barons, 2-4 players take on the roles as the time barons, shadowy figures who have shaped mankind's destiny since the dawn of time. The world’s entire population are simply pawns in their quest to defeat the other barons and become the ruler of a unified human race. War, religion, technology - all will be used in this ultimate battle.
Time barons can decide the best way to exploit their loyal followers and make the most of the many powerful cards they are dealt.
A variety of tactics are available to players at every turn, from placing the bubonic plague on their opponent's robotics lab to slowly kill off the workers, or attaching a computer network to a medieval church to automate the conversion of new followers. In this brutal struggle, many will die... but good planning, quick thinking, and a little luck will carry the day!
