Here's something I struggle with, my kids and video games..... This article over at BBC Future is very interesting and suggests that virtual violence triggering aggressive thought and anti-social behaviour is only a very small part of the story.
"A growing body of research is showing the flip side, though – video
games can help people see better, learn more quickly, develop greater
mental focus, become more spatially aware, estimate more accurately, and
multitask more effectively. Some video games can even make young people
more empathetic, helpful and sharing. As public debate on the subject
is often highly emotive and polarised, and as more and more of us are
becoming gamers, researchers say it is important to move beyond the
generalisations that characterise much of the discussion."
