Well, it kinda does, in a way. While playing violent video games doesn't directly cause violence, it enhances your ability to commit certain actions compulsively when presented with the option. When played enough, the gap between reality and virtual reality gets smaller, and the consequences are seen as less severe. In violent games like GTA or Mafia, where you are able to commit heinous crimes against humanity, the idea of wrongdoing is more and more desensitized in your brain, which leads to a slippery slope of compulsive actions. ie, the way you see choices and objects changes, not for the better.
So, when playing any game really, you have to engineer into yourself a certain mindset, so as to mitigate the effects, such as addiction. Games are designed by dev's to hook you, via neuro-pathways.
This is why videogames really aren't able to be played for more than two hours a day, without becoming a hindrance in your life. Basically, if on a daily basis you think of what you would like to do in a videogame, you have an issue. The more you control the game, and the less it controls you is the more progress you will have in your dreams, as I have discovered.
What do you think?
