The plot of SaGa Frontier takes place in a science fiction/fantasy universe called "The Regions", a group of worlds with varying degrees of culture, unique races, technology, and magic. The game allows the player to follow the exploits of one of seven protagonists, each with his or her own storyline and goal. The game's "Free Scenario System" offers a large amount of non-linear gameplay, allowing the player to freely travel between many of the Regions, interact with other characters, and take part in turn-based combat.
