The Job System is fully refined from FFIII, so Gameplay really isn't a concern.

Some people hate the storyline and characters, though the characters assuredly aren't the emotionless blocks that people accuse them of being (or they just like whining).

The villain, however, is very generic, but that shouldn't stop you from enjoying the game.

However, the PS1 port has a very wacky translation (like, FFIVe quality here), and the sound is definitely downgraded from the original. You may not notice this if you haven't played it on an emulator before, however.

Overall, a decent game. Not really my favorite, but it's still teh awesomes.
