Games in itself don't raise violence on matured minds just the competitiveness of the person playing it,I think that it's very relative,as you see,it's very dependent on how mature the child is,if he/she know that everything that is happening is fake and understands that any action that is happening there is unrelated to real life and that the consumption of the media should be taken as an hobby,just like too much movies or books will push other stuff like responsibilities aside so do games,and so they should be regulated by the parents on time spent on it,this on 8-10 y kids,wouldn't let any 5 y kid play COD.
But every household is different and every kid is different and rules should be made by each parent for each kid,but some just can't or don't want to do that.
