Spielberg talks about the difference between M rated games and M rated movies

“I wanted something that would bring the family together in the same room, standing shoulder to shoulder with four different controllers. There are games that are taboo. And I won’t have them on the premises. I don’t want my kids saying, ‘How come Dad is playing that and we can’t?’ My kids will never go in and take an R-rated DVD and play it. But there is something very compelling and different about the artwork on the box of what might be an M game that could tempt my kids.” - Steven Spielberg
