Era: Medieval Age Expansion invites players to return to the world's first "roll & build" game with tons of new content. Included in this expansion are roads and rivers to connect domains to the world outside their own. Players will discover new structures and develop new strategies as they build their way to victory! With all these new opportunities comes a bit of risk as players will be challenged by a new disaster. Lastly, four scenarios are included in the game to give players an opportunity to become familiar with the new gameplay mechanisms.
