I think the answer to question is No.
However the Psychological studies that have been done prove that violent video games DO increase aggressive behaviors!

There is Positive correlation. (about .3 - .4 If I remember)
To the degree they do so is also dependant on the personality of the gamer.
Surprisingly, Women and Girls show greater increase in aggressive behavior, than do traditionally more aggressive Men and Boys.
Did a reasearch on this in basic Psych 101.
Damn I wish I wouldn't have sold my textbook back.
I do not play video games at all. Only very rarely with my Nephews when I babysit. Violent or not, they're a complete waste of time!!! Get out there and ride your bike or build a model or SOMETHING!
Occasionally they are OK, when weather is bad and there is nothing to do.
