Being exposed to violence at a young age could be a good thing, then you will not underestimate the evil that exists in the world, and how bad people would treat you. My parents wont buy me M games until I am actually considered old enough to play them, by then I will buy them on my own probably, but I got them to buy me Half-Life, Counter-Strike:Source, and Garrysmod because those games are not that bad for me to play.Like Half-Life is just Gordon Freeman shooting some aliens and soldiers, and Counter-Strike:Source is like norse heaven where you fight forever. And Garrysmod is a sandbox game, enough said for that.
