Well the worst period is no doubt something I didn't even play, but of all games I did play......
Bioshock. It was so boring I didn't even make it half way through

From what I have played it would be either I am Alive or Lair. Skyrim had my blood boiling shit ton of times, I was actually afraid that it would brick my console, after so many crashes and freezes. Considering I bought it day 1 full price, and felt like a fucking beta tester it was the most frustrating and dissapointing purchase of the gen for me.

1. Fable 3 (PC).
2. Stronghold 3 (PC).
3. Duke nukem forever (Xbox 360).

Dishonorable mention: Socom 4 (PS3).

Resident Evil 6 or Battlefield 4

I KNEW people would be naming critically acclaimed games! It never fails!

Anyway, for me, it's this game called Kawasaki Jet Ski (or something like that) for the Wii. It was like $19 when I got my Wii so I bought it, blissfully unaware of the Wii's over abundance of shitty shovelware. I finished ONE LAP of the first track, sensed the horrific quality of the game, and threw the game under my sofa in disgust. Later, when I found it, I threw it away.

A game I did not really like was Bioshock. I hated Bioshock it was very boring and I have no idea why a games like Bioshock/2/Infinite receive great review scores, I would not bother with Bioshock Infinite like I did not bother with Bioshock 2. Bioshock was too easy, infinite re-spawns you could practically walk through Bioshock on hardest mode without taking much damage and easily evade those stupid Big Daddies.

Donkey Kong Country Returns (Wii) - I'm still waiting for someone to, without hesitation, disclose another Wii game crippled so badly by try-hard waggle.

Going to have to jump on the Bioshock hate bandwagon I'm afraid. Really dull game.
