7 Wonders 2nd Ed Edifice Expansion

7 Wonders: Edifice allows players to collaborate in constructing communal buildings. If you contribute and the building is completed, you'll receive a reward. Participation isn't mandatory, but opting out may result in a penalty if the building isn't completed.

During each age, when you build a level of your wonder, you have the option to also pay the cost of the current age's edifice card (on top of that level's cost) to obtain a participation marker from the card.

7 Wonders: Edifice contains two new double-sided wonders; one of them, Ur, can only be used with this expansion, while Carthage can be used in any game of 7 Wonders.

7 Wonders: Edifice can be used with any edition of 7 Wonders.
