I agree with Jenny on this one, it depends on the type of game. My first video game was Sonic the Hedgehog on the Genesis when I was 4 years old and I think games like Mario and Sonic are fine for young kids but games like Halo wouldn't be. I was allowed to play mature games when I was 12 but my parents asked me first if I knew the content in the games were fake and not real, of course I knew that lol so I didn't go out and reenact the games.
