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.
I don’t fully understand the question.
I’ve at least liked every game I’ve completed so it’s hard to point to “the worst” one.
I’m asking about a game that you started to dislike while playing it, but continued to finish the game because you wanted to see it through to the end. I would also say I’ve enjoyed 99% of the games I’ve played, so I was trying to think of games I’ve completed that were honestly just not good
