FFIII certainly does seem to be one of the most overlooked games in the series and I knew nothing about the game until I played the DS version. It's a good game; I wouldn't consider any of the FF games to be bad as it were, but I think it's probably one of my least favourite entries in the series. As Necronopticous said, it suffered quite badly from some issues in the DS version that made it unbearable at times (similar to the PSX version of the SNES games). Good game, but not great, I'm afraid.

Also like Necronopticous said, I certainly don't see it being updated within the next five years.
