The 4 Xs of the traditional Civilisation game are: eXplore. eXploit. eXpand. eXterminate. By adding another option: eXcavate, 5X goes one better! Outthink your rivals, call upon Great Leaders, build glorious Wonders and all in under half-an-hour; 5X challenges you to juggle actions and resources without letting your competition get too far ahead. Can your Civilisation build a legacy for the ages? 5X is a simultaneous action selection game. Over seven rounds, players will use a limited range of cards to collect resources and build Wonders in order to gain the most Victory points at the end. —description from the designer
