"Illusion of Gaia" was scored by Yasuhiro Kawasaki. Moto Hagio, the influential manga artist, is credited with the character designs. Novelist Mariko Ōhara worked on the story. The game is often considered an unofficial trilogy along with two other Quintet games, "Soul Blazer" (1992) and "Terranigma" (1995).
