The only thing that doesn't vary is that the best course of action is to not play them at all.
I couldn't disagree more. I read a study just last year that children that play video games have better hand-eye coordination than children who don't.
There is nothing intrinsically evil about playing video games just like there is nothing intrinsically evil about swimming, taking a walk, eating cheese on a regular day, or chewing gum. You can't say it's better "not" to do any of these things.
