There are job classes, though without the particular outfits and there are four crystals as in practically every Final Fantasy. The plot features the quest to protect the wind crystal after the others are stolen by a new enemy, a strange alien with advanced technology whose base is located in the black moon, a natural satellite of planet Gaia.
The story has its fair share of humor and amusing characters especially Pritz and Rogue. The plot is easy to understand even if you haven't played the game, but the references would be lost.
Overall it seems this anime has received more criticism than praise, possibly because people expected a sequel with more connections to the game. But if you look at it as a strand alone Final Fantasy story, it's not bad.
The art and sound are not the best, but to be fair the anime is rather old and has decent art for its time. Despite it not being one of the best anime out there, it's still enjoyable and I recommend watching it with an open mind, being ready to judge it on its own instead of holding it against the game.
