Tactics Ogre is a Strategy RPG made by Quest and released by Altus. The game was innovative in its branching plotline. Crucial decisions made in the game determine the path of the story, the members of your army and the ending sequence. There are always multiple endings with radically different outcomes.

For eighty years, Valeria has been in constant strife, and its three leading ethnic groups all claim leadership. The three factions are:

Gargastan: While these people make up 70% of Valeria's total population, they suffer constant inner struggle between moderate and radical theorists on how government should best be handled. This weakens what would be a dominant majority.

Walstanian: An oppressed minority of Southern Valeria, making up only 10% of the population. Their suffering is the catalyst to the plot in Tactics Ogre.

Bacrumese: These are generally the more "elite" of Valerian society, making up a solid 20% of its people.

Mighty King Roderick, aided by the forbidden powers of the "Hell Gate," is able to dominate the people until Dolgare of Bacrum successfully leads his army to defeat Roderick and his dark powers. With the king dead, the charismatic Dolgare claims the throne as his own, and is able to end the struggle between the ethnic groups. Under King Dolgare, the rights of the people are preserved, and internal struggles in Valeria come to a temporary halt.

All is right until the entire royal family is lost due to a string of accidents. Because the late King Dolgare had no living heirs, the ethnic groups once again struggled for leadership: Bishop Branta of the royal court, Cardinal Barbatos, dictator of the Gargastan people, and Duke Ronway, representative of the Walstanian minority, all fought for control, but in the end, Barbatos and Branta stalemated. In order to preserve their power, the two men took separate measures: Cardinal Barbatos sought an "ethnic cleansing" policy and slaughtered thousands of innocent Walstanians and Gargastans, while Branta received aid from the Roslolians, the greatest order in all of Lodis.

The separation of the three races thus sets the stage for the beginning of the game. The player is greeted by a collage of scenes depicting the Roslolian Order's mysterious actions in Griate, home to Denim Powell, Kachua Powell, and Vice Bozek, the main characters. Denim and Kachua's father, Plancy, was kidnapped by the enigmatic Lans Tartare, and the three heroes seek vengeance against the dark knight.
