Museum: The World's Fair
The World's Fair Expansion introduces two new mechanics to Museum.
The first new mechanic is the 'Pavilion' which introduces new shared objectives.
The second new mechanic is 'Loans.' Loans allow you to send an item to another player's museum which will benefit both of you. This is not available in the two player game.
The World's Fair expansion also includes three tower boards as well as additional events, personnel, and character cards.
