See if you ask me, what is overrated is Skyrim hands down, but it isn't something I disliked.

GTAIV might be the one I think is highly overrated and I disliked, but from an objective view point, I can understand why overrated, hence why I picked Skyrim. It confuses me a bit why it was rated so highly. 

I'd also add FFX.  Ridiculous characters and writing; Tidus is shoehorned as the main character when that title clearly belongs to Yuna, not to mention he's a pitiful, self important, whining shit that is the definition of  "hateable charcter"; Rikku could have never existed and the story would be exactly the same.  It had abysmal dungeons (most notably that abomination with the tile nonsense).  It had decent music, great graphics and battle system but for fucks sake look at Seymour.  Look at him.  Sephiroth is bad but damn Seymour.

Bioshock Infinite and The Last of Us.

I don't dislike these games at all, but I think the praise these games got were a little overblown.

I've heard mixed things about the game, but I've never actually played it myself. It sounds like a game I wouldn't really enjoy.

GTA or Elder Scroll games are way too overrated, especially the recent ones but Watch Dogs takes the cake.

This and Bioshock

In my case, it's The Last of Us. I quit playing it the first time because it was very boring and repetitive. Then I picked it up again on PS4 and disliked it again, but thus time I forced myself to finish it. I wanted to give up on several occasions, but I endured...

The second vote would go to Halo, but it is an unfair comparison, because I don't like sci-fi FPS in general, while I reallg do like third-person games (both shooters and adventure games).

I agree with you on RDR, and am surprised many people like it. What killed it for me is about a dozen cattle driving missions, that dragged the ending unnecessary. 

Oblivion will probably always be at the top of my list. Fuck that game.
