SaGa is a series of role-playing video games developed and published by Square Enix. Its first game premiered in Japan in 1989, and SaGa games have subsequently been localized for markets in North America and Europe across multiple video game consoles since the series debut on the Game Boy with The Final Fantasy Legend. The original Game Boy trilogy was released outside of Japan under the Final Fantasy brand for marketing purposes but was otherwise unrelated to the franchise. Several titles remained exclusive to Japan in their original forms, only coming to other territories with ports or remakes on later platforms. Most games have their own settings and gameplay mechanics. Series creator Akitoshi Kawazu led or advised the development of most of the games.
