The only time I would turn on a game is when I make big statements when I just started it then realize that the game fails to be what I was predicting it to be. For Oblivion I initially thought "Morrowind with better graphics! It can't be bad", but then I kept playing and realized how many aspects were taken away and changed for the worse. I still enjoyed the game, just nowhere as near as I expected to or Morrowind. Same with GTA4, except that did turn out to suck. I remember 30 hours in and I was still waiting for some event to happen to make it interesting, but it never came. Saints Row 2 had an interesting turn before I even was able to control my character.
