In Analysis of Computer Games for Violence Potential, forensic psychology expert

Dr. Julie Armstrong writes:

When a person begins spending an inordinate amount of time playing computer games, we can be sure that they are struggling to keep these violent feelings under control. When a suspect writes his own versions of the game, what we may call add-on scenarios, we can analyze them to better understand this gamer’s emotional world.

In addition to the main play of the game, the gamer puts in subtle and obvious details that give us information about how he perceives the world… his world. From this information we can make some interpretation about his state of mind. When integrated with other information we have, we may be able to take actions that prevent the acting out of violence.
