I think the first time I recall being really dissapointed in a game was when I bought Dinowarz: Destruction of Spondylus. The box art was deceivingly cool, and the thought of playing as a mecha-dino had me excited. Unfortunately, after spending some time with it and being totally disgusted with my waste of money I never picked it back up.
Here's a link to a "review" that some guy did that basically felt the same way I did. Has a couple screen shots to really show the crap that it was.
