A Total War Saga is a sub-series of games in the Total War series.
Sagas are the third type of Total War game. So far Era Total War games focus on entire historical periods and their peculiarities. Character games devote time to pivotal personalities that changed the course of history. Sagas will focus on the missing link: Pivotal moments in history that, should they have happened a little differently, would likely affect the shape of the world and its nations.
