be fine. you may do all your chores and what ever else your told to but every kid says how mature they are,i did it to and that was many many years ago.there are ratings for a reason,although lots of parents don't seem to care some do.so if your parents buy it for you then that's up to them,personally i wouldn't sorry. I played cod when I wasn't 13. To be honest, it's your parents' decision. Hell yeah I would let you play it, because it's the hit of the Ps3 and Xbox along with other major titles. Honestly, you're just staring at a screen, pressing a few buttons. I doubt that would inspire someone to go on a bloody killing spree. anyone can play CoD as long as there parents let them or they don't annoy people talking stupid things on the mic . Try to win and you will get better online . It's a game so as long as you have fun playing it it's ok If your parents say that it is ok then it is entirely up to them.. the age ratings are more of a guideline for people wanting to play them. My mum was really harsh on me when I was younger with age ratings on PS1's and 2's , but as I became more mature she let me onto them (It's lame, I know) Still, so long as you aren't one of those kids that scream "OMG YOU ARE SO GAY" to
