The most disappointing isn’t exactly the worst. These games tend to be over-hyped and turn out just mediocre when they were claimed to be something amazing by developers.

Disney Epic Mickey

With a game that was supposed to be so amazing, and well, epic this game really was like a punch in the gut. With a bad camera, muddy textures, and poor combat and controls, Epic Mickey should have come out next spring with more polish. This just goes to show that a superb idea can fall flat.
