"Video games are fairly predictable in most respects, with storylines and gameplay that rarely break the mold of the genre. Maybe that's why the following five games make you want to yell "WTF?!" when you experience their respective twists in the formula. With such originality, it should come as no surprise that these games have been touted as some of the best ever created. Then again, not all of these moments have been deemed beneficial to the game's success."
