In a distant future, psychic powers make warfare obsolete across Europa...until the ruler of Europa disappears, plunging the entire moon into a succession crisis. Psychic scheming meets dynastic intrigue in this card game of prediction and influence. Players vie to become the power behind the throne, predicting who is next in line to become ruler of Europa and manipulating the court to make those predictions come true. At the start of Heir to Europa, players predict how many coteries they'll win to their side. Each turn, you play one card from your hand, representing your soliciting help from a political ally. If that ally has a special ability and their faction is still loyal, you may activate that special ability as well. Each time a faction comes into play, its loyalty lowers by one. You must decide when it's best to play a lower value card to use an ability while you still can.
