I really don't like this idea so it certainly isn't for me. Do you know how I play GTA? I steal cars and proceed to drive around the city obeying all traffic laws for a few hours. I'm not even joking, that's how I play the game. This game makes me a little bit sick but um

I guess if some people want to play it, its their money.

As a parent, if my son wanted this game (when he was older than 5 obviously) I would probably ask him why he wants to. Maybe open the way to communication about it. Or maybe he'll just scoff or eyeroll at me. I mean I play games where you kill people, it happens in FF games, I'm basically commiting mass genocide in spoilers in caseXenoblade but I know why I play those games and the main motive is not "to kill things". So I would want to hear his thoughts about why the game appeals to him, which I'm guessing would probably be along the lines of "I get to shoot things". But who knows!
