Just a thought that keeps crossing my mind. I wonder if choices made in properly designed video games could provide clues about the potential for violence, in the gamer. Can gaming choices, or more likely patterns of choices, be designed to be indicative of mental issues, such as psychopathy - e.g. [just a wild guess] the choice kill one person blocking your path as opposed to a group of children standing nearby? Or perhaps given the choice to kill at the cost of winning. That sort of thing. I know of plenty of research regarding any potential link between gaming and violence. But I have never heard of research investigating any predictive value of gaming. Taken one step further, can games be designed to help parents test the mental health of their children, so as to identify potential problems early; possibly to include conditions like mild autism or Asperger's Syndrome?
