Another beloved RPG franchise from Game Arts, probably best known for the Lunar series (which was a fan favorite on both the Sega CD and the original Playstation). Grandia isn't quite as well-known, however it is no less worthy of your time if you love quality JRPGs with a sense of fun and adventure to them.
The game was published in the US by Sony and in Europe by Ubisoft as a Playstation exclusive. There was also a Saturn version that never made it out of Japan, along with a Saturn-exclusive bonus disc known as "Grandia Digital Museum" that serves as both an extension of the original game's storyline and as a literal digital museum, showing off concept art, drama plays starring the characters, minigames and other features.
