Imagine putting an M-rated game into your game console or visiting the website for an M-rated game and seeing a screen like this. It looks a whole lot more complicated than putting in a date more than 17 years ago, doesn't it?
People who keep running into dead ends in mazes are more likely to run into dead ends in life, no matter how old they are. Completing the Porteus Maze Test
is like scoring golf-the higher score you get, the more likely you are to be delinquent or truant. This measure would not stop everyone under 17 from playing an M-rated game or seeing the website for one, but it would be very effective at stopping both children and adults who are impulsive, incapable of delaying gratification, possess poor planning ability, poor judgement, and/or poor foresight, mental problems which would make them more likely to commit violent acts.
Now, I know what you're about to say. You're planning to tell me, "I played Grand Theft Auto when I was in elementary school along with several other first person shooters and I turned out fine." Well, if that's true, you probably would have passed this test with flying colors. But not everyone will.
Of course, a new maze would need to be procedurally generated each time this test is performed.
