The game has several unusual elements placed together. First, an alternate-history future where the Napoleonic Empire has been victorious for hundreds of years. Second, a cultural fascination with an ancient Aztec game known as Ulama, of which a variant known as Boile de Muertre is played by the noble and royal houses of the Napoleonic Empire. Third is a play zone-signficant, deck-constructed card game played with Uno cards to determine the action and resolution of the Boile de Muertre matches. After the card game matches, the characters (abstracted nobles in the Napoleonic Empire) narrate the results.
The game suffers from poor organization and rather strained relationships between the major components.
