I would suggest buying it. It should be fairly cheap now.

Like Ichimonji said, its dialogue is terribly cliche. And so is its character design and storyline too. What a surprise, the red guy uses fire and the green guy uses wind, and so on. You can probably get used to that, after all, you're here on a Final Fantasy site. The battle system is really awesome though. In order to do any significant amount of damage, you need to time your combos properly and hit the button at the right moment in the animation to extend the attacks. You can transform into a dragoon and use new and different modes of attack, which adds a whole spin-off to the battle system making it less tedious, kind of like how Xenogears uses Gear and human battles. It's also quite long and provides a good challenge. The character graphics aren't so good, but you'll find yourself getting absorbed into the background graphics. Music and sound effects are nice, and you even get a catchy tune to listen to when you go into the menu.
