halo always came off as a bit of a cartoon to me. The enimies look like something of cartoon networks ben 10 and the storyline is basic and not graphic at all. All Halo has at all is combat, so it really depends on how you feel personally about fighting. Although Halo Wars is a pure strategy game, there's not really going to be much hands on fighting anyway. I would say yes, its appropriate. But games like Gears of War 2 and Fable 2, absolutley not. In the end it's your call though. Hope this helps
