Grand Seas Adventure: Gaiden

Daikoukai Jidai Gaiden (Uncharted Waters Gaiden) is a strategy/RPG game developed by Koei for PlayStation. Players select from two playable characters—Miranda Verte or Pietro Konti—and manage a fleet in 16th-century Age of Discovery settings. Core gameplay involves navigation, trading, battles against pirates, treasure hunting, and exploration across open seas and ports, with ship upgrades, skill trees, and reputation-building systems. The story follows the protagonists' personal ambitions in a world of commerce and conflict. What makes it stand out is its simulation depth in maritime logistics and decision-making, expanded character progression, and improved visuals over prior entries, offering immersive role-playing in a vast ocean environment with multiple scenarios.
