SaGa (サガ?) is a series of science fiction open world role-playing video games produced by Square, now Square Enix. The series originated on the Game Boy in 1989 as the creation of Akitoshi Kawazu. It has since continued, spanning multiple platforms. The series is notable for its emphasis on open world exploration, non-linear branching plots, and occasionally unconventional gameplay. This distinguished the series from most of Square's titles. There are currently nine games in the SaGa series, along with several ports and enhanced remakes.
