Century Big Box contains the three titles in the Century game series — Spice Road, Eastern Wonders, and A New World — along with all promo items released for these games and a new mini-expansion, Golden Deals. Each game can be played independently, but they can also be combined with one another or played all at once, giving you seven different ways to play. The Golden Deals expansion consists of clear cards with effects on them, giving you something new to acquire and allowing you to modify the cards in play.
