Your most disappointing game ever?

[SvennoJ]

Zelda Skyward sword.
I had such high hopes that it would be the next Windwaker. I could not finish it in the end after picking it back up 3 times before finally trading it in, good riddance. Ugh, so much wrong in one game. There was still stuff to like in the game, yet after expecting so much it was the biggest letdown.
