My parents used to not allow me play rated M games, but after a few months, they realized that most rated M games are not bad. Of course, they didn't know which ones but I had been asking them if I could buy Halo Reach (not a very good game, but I was a noob at the time; the other Halo games are much better) and eventually they started watching gameplay, etc, etc, and they finally let me buy it. Then I got into more halo games. I bought Halo 3 and Halo combat evolved anniversary (same thing, just better graphics) so I played through the campaigns, did some multiplayer, etc, and I then realized that Halo games are not bad at all. I don't see any point in rating them M for mature. I mean, sure there is a little bit of human blood in multiplayer when you are killing each other, but in the campaign there is only alien blood and the graphics (for halo CE) are terrible because it is an old game. (MINOR SPOILER WARNING) Throughout the campaign, there is an alien/zombie infection called the Flood. They are basically zombies from space. They have disgusting green skin, but no human intestines or blood is shown. The Flood is the reason that on the back of the case underneath where it says "M" it says "BLOOD AND GORE". There is no real "GORE" shown, however. For some reason, it seems to me that anything with some type of zombie-plague/infection just HAS to be gory. They aren't really actually gory though. I consider gore to be intestines being shown or something along those lines. I am a Halo fan and my parents might not let me play this game if it had strong language and what I consider gore (which doesn't make sense to me because of how much of those things I have already seen/heard and because of how much the world can be corrupted these days). I used to hate gore, but seeing a few war films has desensitized me a bit, but anyway, when I was a newbie to this kind of stuff, I was cautious about this game because I noticed that it said "BLOOD AND GORE", but it's never really as bad as you'd think. Sorry for the gigantic review, but I hope I can help some people make decisions.
