Uh oh. Someone's about to die. It's all up to you, as the player, who gets to survive and who doesn't. Who to choose, who to choose, the timer's running out, you better think fast! Or, you can just pause the game, and look up the results online.
Why bother making that rash decision yourself, when you can just Google the end results of either decision before choosing it for yourself? Perhaps this isn't always a problem for everyone, at least for the players who decide to live with the results of their actions, but humans are perfectionist creatures that can't handle loosing a dollar out of their pockets one day, you think most people are going to handle being responsible for killing off their favorite game character?
But that doesn't necessarily mean you'll get the results you want anyway from cheating. Some games like Infamous and Call of Duty: Black Ops II implement a sort of "choice-less choice" in their campaigns that especially encourage people to look up an action's result online.
Within Infamous, main character Cole had to choose between saving his girlfriend or several doctors who could help save the city. If you chose the doctors, your girlfriend died. If you chose your girlfriend, she still dies. You see, the game throws a curve-ball at the player depending on how you play that girlfriend Trish will be one of the seven doctors if you tried to save her, and the person you though was her being someone else entirely. If you save the doctors, Trish isn't among the doctors and dies from your lack of saving her. For lack of a better word, what a gut-punch Sucker Punch!
