For a major game, it'd have to be... Halo 3. More because of the story's plot. It sounds like a drama/horror in the later half and a substandard survival-of-the-planet for some of the first levels. :] the rest of it's fine though.
As for a more minor game's letdown... Perfect Dark Zero. I got the first game at age seven and not even Portal can stand to its majesty. Playing the second of the two seemed kinda like playing with wax figurines that are about to melt
