I have to say Assassin's Creed II. Probably cause the disappointment factor was so high due to the incredibly inflated hype. Confusing, all filler, repetitive and hugely contrived, I felt like I was a pawn for falling for it. What was more frustrating was the potential is so great. I just don't get it. Is it really fun for you to play? Outside of moment feeling powerful in combat or the incredible climbing and city models and vistas which all get old after 5 hours? Maybe I just got a bad taste in my mouth from the beginning during the virtual sex scene. I never knew penetration could be so disturbing. Couldn't wait to remove all the files off the hard drive. It was that bad for me. After several hours I had the feeling I was wearing a straightjacket made of burlap while I was playing.
