I would have to say The After Years.
As a big fan of Final Fantasy IV, this sequel really just gives you a taste of something that could have been amazing, the revisiting of an epic world. Instead, we got to replay the stories of different characters starting from level 1 every time and having to obtain startup weapons every time. To compound to that we had a sub-par team work on it, sucking out all the awesomeness of FFIV in the process. Had I wanted to spoil the story for you guys, I would tell you what the main story told, and that was a cheap redo of the original story.
Runner up: Punch-Out!! (Wii)
The original another favorite of mine, though this game comes close to a great experience, the whole "American Daily" feel of the first game was entirely shoplifted, as well as the gripping humor of the first incarnation. Nevertheless this game has its qualities so it isn't an utter disappointment.
