Game of Crowns (2015)

Description from the publisher:

Many will sit on a throne, but only one can wear the crown!

Long ago, the great Ruelen Empire was united under a single banner. In the aftermath of Ruele's Doom, the Empire was shattered, torn apart into nine houses each led by one of the Emperor's former council. The realm was thrown into bitter conflict as each of the nine houses vied for power over the others – each seeking to reunite the broken Empire under their rule. This conflict became known as the Game of Crowns.

In Game of Crowns, each player takes control of one of the nine noble houses. During the game, players can exchange cards and favors through diplomatic relations, or directly attack opponents through warfare in order to take what they want. It will take clever planning, skillful negotiation, and daring confrontations to gain dominance over your rivals and seize the crown!
