Witcher 3. I bought it because some were saying it's one of the best "story" of all time, and the game of the year.
Expectations were not met about the story. I still enjoyed the gameplay and gladly finished it. Geralt was an awesome character with a great back-story, but relationships were pointlessly superficial, and the main story was so cliche it started to feel like harry potter once we entered the third act. Adding more and more grandiose stakes towards the end just made it feel even more cliche.
Same opinion of Dragon Age, Fallout 4, and pretty much any RPG. Great games, great world building, but the actual story never meet expectations. Maybe it's just me who dislike RPGs mandatory story tropes but still enjoy the game genre.
