The Eiketsuden series (英傑伝シリーズ, lit: "Legend of a Brave Hero" series) is a franchise name created for a specific set of historical simulations from Koei. These titles take place in either the Three Kingdoms era of China or the last hundred years of Japan's Warring States period. Unlike Romance of the Three Kingdoms or Nobunaga's Ambition, these titles have a focal protagonist and strive to tell the narrative mainly from their perspective. Each title plays in a similar manner, somewhat resembling the gameplay found in Nintendo's Fire Emblem series.
