This post came to mind after I played the new MW3 campaign. For me personally it has to be Wolfenstein: Youngblood. That game was a complete disappointment compared to the rest of the new Wolfenstein games. The only reason I ended up finishing the game was because my friend and I were playing it together and decided to tough it out and see the end of the story. Gears of War: Judgement is another dishonorable mention. A game that I did not like at all, but continued to finish it solely because I had played every other game in the series so far.
This was the answer I was going to have, and believe I have made this answer many times in the past. I was working at Gamestop at the time, and was able to borrow it.
I beat it the same night, as it is a really short game. But by far one of the worst I’ve ever played. I had super high hopes because the trailer made it look like a really cool game.
