A new expansion is coming for Through the Ages: A New Story of Civilization from CGE. It's called Leaders & Wonders and, as you would expect, it adds leaders that you can recruit as you build up your civilization, as well as amazing wonders that they can construct. Of course, war is a major player in all things world history, and there's new cards for that as well.
