The expansion includes 27 new units, 13 new buildings and nine new Wonders. There's also nine new civilizations, including Carthage, the Netherlands and the Celts. Along with two new types of city-states: mercantile and religious.
Scenarios include the medieval period, the fall of the Rome and the (very cool sounding) Empires of the Smoky Skies, "a Victorian science-fiction scenario."Oooh!
Most importantly, however, is the return of religion and the salvation or subjugation of the populace through its means. As players enter the Renaissance, spies can be unlocked to change the course of history through surveillance, theft and the always good fun of a coup. Sounds like a missed opportunity for an Assassin's Creed crossover if you ask us.
