The game is typical JRPG on the Super Famicom and an Action RPG on the Saturn. What you want to check out before the game is at least the original manga, there's 6 volumes in total and both games take into account only the 3 first volumes (also the opening theme of the anime is freakin' beautiful).
If you want to go for the games, the Saturn game was released in the US by Working Designs. The SuFami game was never released outside Japan, though there is a fan translation available.
