The plot of "SaGa Frontier" takes place in a science 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. "SaGa Frontier" enjoyed commercial success, having sold over one million copies. The game was generally well received in Japan and has been re-released under a few best-seller labels, as well as the PlayStation Store. However, it received largely mixed and average reviews in North America, mostly due to its ambitious Free Scenario System.
