Crisis Core. I was so hyped to play it since everyone was raving over it saying how amazing it was and it was even better than FF7 itself, naturally I was bitterly disappointed. I've since eased up a bit on the hate for it, and it's honestly not that bad when compared to a true soulless piece of cancer like Advent Children or Dirge of Cerberus. Genesis still sucks though.

I tried playing the DS remake of FF4 and found it underwhelming in pretty much every regard, I got as far as the mom bomb or whatever boss fight before quitting.
