The Last of Us, definitely. I had it pre-ordered but kind of started losing interest. Then I watched some gameplay and decided I would just wait to rent it instead. What a boring, tedious game. I loved everything about the game (except the ending) except for the gameplay. It's boring.
Naughty Dog had such a great thing going on with the presentation, story, and characters, why did they have to fall back on the same tired cover based third person shooter gameplay that the industry is already oversaturated with. Its attempt to change up that gameplay just fell flat, mostly just working to make it more boring and tedious than if they had just gone a straight action route.
This covers a lot of what I didn't like about the game, the only parts I disagree with being the story.
