I don't necessarily disagree with your point of view, but it would be good to find sources of research not provided by theesa.com (The Entertainment Software Association).
MORE importantly, does anyone know of research done exploring a possible impact of these video games on mentally unstable people??? I think it would be very, very hard to get a study like that approved, of course.
The question we might be asking, though: Violent video games may have no real impact on normal function individuals, but what impact do they have on a child or adult who has mental illness, such as multiple personality disorder, anxiety, etc...?
