If video games actually determined our real world behavior, we wouldn't be violent, we would be obsessed with powerwashing and all have CDLs.

edit - Yeah I play video games with violence too, my point is that video games are a mirror that exposes a less brutal image of ourselves than we are convinced of. The truth of what we desire is as often silly or altruistic as it is selfish or violent, even in the realm of fantasy where the violence is unreal as everything else.
