Návarchoi is a low to moderate complexity, card driven game that recreates the challenges of fleet command in the age of the trireme. Play is fast and furious, where players use a limited supply of cards (based upon their fleet's quality) to issue strategems to their respective fleets. The fleets are activated using impulses where they move and attack using similar mechanics to ram, rake, and fire missiles. The cards can also be used as events that provide period flavor.
