Well done sir. I was also playing Halo and GTA when I was 10, my father sat me down and talked to me about what was going on, reality vs. fiction. We'd also watch Terminator, The Matrix, and Tarantino films when I was growing up. Not to mention I have been shooting guns and hunting from around that age too. It all comes down to parenting, with that being said, some kids should NOT being playing these types of games. However, it's up the parent to figure out whether their child can handle it. Folks need to stop blaming the content and take a look at themselves, if your kid is having issues with the content, talk to them. Be a parent.
