7 Wonders: Leaders will add 40 new cards to the base game of 7 Wonders, comprising four new guilds and 36 new, white "Leader" cards. At the start of the game, each player takes a hand of four leaders and may play one at the start of each of the three Ages. Unlike the standard cards, leaders cost money (not resources). The expansion will also come with a new Wonder - the ancient city of Rome - and reportedly contain some 6-gold tokens for more efficient money-management.This expansion is in French!
