I doubt that 10 years old are smart enough to make a difference between real life and game universe. I started playing Modern Warfare 2 (my first 18+ video game) at the age of 9, and I was dumb enough to believe that the game's events happened in RL. And I'm sure I'm not the only one here. I also doubt 9 years old know what killing is. It's like saying we should show porn to 10-years old. In both cases it's mature content, for a reason.
