While FFVI is by no means the best FF ever, it is an experience that shoudn't be missed by anyone.
Now on to the serious review...
Gameplay: The battles are the old-fashioned kind, turn-based in 2D, but that's not always a bad thing. It's fun to keep it simple sometimes. You can hold a party of up to four people, which should include at least Cyan and Sabin at every possible moment. You take the role of The Returners desperate in hopes of stopping the evil empire (no, the Yankees aren't in this game) from taking over the world. It's somewhat generic, but oh so fun. I won't ruin it for you. There are of course, twists.
Audio: Great sound! Nobuo's talent really shines through here, and this is some of his best work outside of FFX, FFVII, and FFIX. I think the word/name Nobuo is plenty enough of describing the audio in this game.
Graphics: Well, good considering the platform in which they are intended. It's obvious that they're somewhat outdated, but the message will get across, I promise. As in some other previous FF's, the enemies are almost completely different graphically from the team.
That's all you get with the new review system! I highly suggest getting this game!
