Why are reviewers putting so much emphasis on story rather than gameplay/replayability?

Because story is just as important?

If a game wants to tell a story, if the story is an important part, but fails, it stands to reason that it will eat a good chunk of the score, no matter how good the gameplay is.But if a game is all about gameplay, like any Mario game, or even better titanfall, the story isnt as important to the score as gameplay.It really depends on what the game is trying to achieve
