What I think would be a good add-in is a blood setting (High, Medium, Low, and Off) to make sure gore isn't a problem, High for those who love, well, lots of gore. Medium for those who don't really care about it. Low for those who don't love it, but don't mind it either (like me). Off for those who can't or don't play gory games (I honestly think most FPS's should be 13+, not 4+). As far as swearing goes I hope it's like HALO, because I think we all know it will have swearing.
