It found that, regardless of gender, designating games as Mature or Adults Only made kids desire acquiring and playing them more.
I'm Peter G, and this is the "No Shit!" News At Nine.
Back in the early days of the Sega Genesis, RazorSoft came up with a game called Technocop. It was pretty generic. So they upped the gore and slapped a label on the package, saying it was inappropriate for gamers under 13. Orders for the game tripled overnight. The head of development at Williams, when he saw Smash TV played and the eyeball that flies up towards the viewer when you step on a mine, supposedly said, "That's $50 a week!" In junior high, I was the only kid in my class who hadn't seen the Friday the 13th and Nightmare On Elm Street movies made up to that point, but not because of age restriction, but because splatter movies didn't appeal to me. Kids do whatever they can to get stashes of Playboys, get in the parents' liquor, whatever they are told they can't have just because it is not appropriate for their age.
How, exactly, are the conclusions for this study a surprise to anyone paying attention? (Or even that remembers their own childhoods?)
