Fallout 3 on PS3. Then I played the GOTY edition on PC and loved it.

I found GTA5 so boring that after 8 hours I gave up and swapped it for Borderlands 2.

Skyrim.

Ocarina of Time.

GTAIV! I mean, 98 on Metacritic for that game? Give me a fucking break.. -_-

Bioshock Infinite, it was so promising yet delivered so little.
GTA 4 - Most boring GTA ever
Uncharted 3 - When i finished it I just felt dissappointed, I guess I expected too much after Uncharted 2.
Halo 4 - Worst Halo in the series (still a good game though). Singleplayer and Multiplayer were very lacking compared to the other games.

GTA IV. Reviews were out of the roof, but I bought it on steam back in like 2011 and got very bored very fast. Game took itself WAY too seriously.

I did not get GTA V until a few weeks ago because I thought the same thing was happening, so far I am very happy with it, much improved.

GTA4: Even if I dislike a game I can usually see why someone would like it. With this game I can honestly say that it does not have one redeemable thing about it. Graphics? Meh. Story? Never played enough to find out but my brother couldn't even tell me what this game is about. Gameplay? The controls ruin any chance of having fun.

Just a really terrible game.

A LOT.
I got too much to list and will probably get banned for instigating a flame war.

Dark Souls. I found it to be sluggish and clunky... Very gray for my liking as well.

Skyrim follows it, I couldn't get into it because I felt it was too slow and boring... Should've given it a second chance? Nah.
