I don't know....there have been so many good games this year, I just haven't had time to play the bad ones....I suppose it has to go to Prince of Persia: Warrior Within since I got all the way to just before the last boss when I ran into a glitch that kept me from going any further, it even did the same thing to my earlier saves.  Turns out, it's a well known glitch, and I would have had to start that entire crappy game over.  I resolved to just watch the ending on youtube and go onto the Two Thrones, which is a MUCH better game.
