Dishonored
Most games on other lists weren't advertized as revolutionary, Dishonored was. Then it backed it up with good pre-realease story videos. Then it actually came out and was really bad(compared to how it was advertized).
AC3 because conspiracy theorists have made huge myths regarding the founding of America and Freemasons(Assassins or Templars) and this game about Assassins and Templars refused to use any of those.
On the opposite end Black Ops 2, despite fake Arabic in Lahore, was very good and the first time a military FPS(that I have played) made an effort to make a good and likeable villain.
Another one was Spec Ops which completely lived up to expectations even if it was a suicide attempt from the publisher's point of view(deliberately repetitive shooting to make a point, deliberately trying to look like Call of Duty to be able to pull off that point, no chance for sequel, a story so depressing that most players won't want to play it again to see alternate choices and designed to anger certain kinds of gamers).
