Concordia: Roma/Sicilia is an expansion for Concordia that provides a double-sided game board for two different experiences:

• In Roma, you build the eternal city with famous places like the Colosseum, Forum Romanum, Circus Maximus, and Pantheon. Send your colonist ships abroad to gather extra benefits.
• On the island of Sicilia, coincidental eruptions of Etna may hit you. It's a new element of luck, but Sicilia can also be played without that option.
