The language, what language, the language is few and far between from what i hear. The gore is, well not very gorey really. I mean, sure it's bloody, blue, red on soldiers, but anyway, even the gorey blood is pretty much idk simple. There is no sexual content, nothing close to GTA, the language is mild, very mild in fact, that alot of times, the soldiers don't even say the words, but you imply they're there, i guess, blood is ungruesome, and you're killing aliens, not humans. From what I see it, Halo isn't even as bad as Goldenye, which was on an older system, N64, had less detailed blood, and alrigth, so it didn't have any language from what I remember, but I've seen PG movies worse then halo, i've seen Teen games, such as Splinter Cell that are worse. I have no idea why they gave this game this rating. Plus, for some reason, everyone thinks ooooh, it's rated R, it's rated M, if you play it ur unchristian that is not true. Guess what, our youth group even plays it together during camp. Crown college, a "christian college", they come to our youth group a few guys, they have halo tourneys there all the time, our youth pastor plays halo, he has halo 2 reserved. So, anyway, from what I see, halo's not bad, until society, and really strict christains start picking on it.
