In Utawarerumono, the player takes the role of Hakuoro, a mysterious masked man who awakens one day in a strange village without having any recollections of his past. Soon he discovers that the country inhabitants are being oppressed by their emperor. Hakuoro organizes a rebellion, and eventually becomes the emperor himself. Determined to bring peace to the world, Hakuoro must nevertheless fight against countries who oppose his benevolent rule, and discover the truth about his own past in the process.
Utawarerumono is a turn-based tactical RPG with elements of a visual novel. Much of the narrative develops through text and still images, with the player being able to make a choice from time to time. Battles occur as dictated by the narrative. The player navigates the characters on the battle field, attacking enemies when they are in range. Experience points are gained after the victory, and are distributed to raise the parameters of the characters.
The original PC version has explicit sexual scenes, which have been removed for the PS2 release.
