Legend of Dragoon. Even thinking about that broken game makes me cringe and smile at the same time. You think you've heard bad voice acting? if you haven't played LoD you have not. One playthrough, and you will weep with joy for Tidus' whiny emo voice in FFX. And the totally useless (yet somehow badass still) dragoon transformation gimmick. wow. terrible.

Oh, and i cannot forget True Crime: Streets of LA. Hate me all you want, for some sick reason i enjoyed this game. I equate it with people enjoying Meth, or hookers. It's shameful and wrong, but you can't deny what you enjoy. Horrible, Horrible game though.
