It's the era of the Second Han Dynasty, and China is being overrun by powerful warlords. A struggle for power among the court families has spawned a time known as the Three Kingdoms, and it's up to you (as the current ruler) to restore peace to your troubled country. Rebuild the land by creating a strong military or try to outwit your opponents using negotiation. Sangokushi IV (Romance of the Three Kingdoms IV: Wall of Fire outside Japan for PS1 and Saturn) is the fourth game in Koei's Romance of the Three Kingdoms series. Sangokushi IV was the first game for the Playstation & Saturn consoles and the last in the series to be released on PC in the U.S. until Romance of the Three Kingdoms XI.
