I would just like to say, I see no reason for this game to be rated M for Mature if it had very little M rated material to show for it. It has just blood and violence when you have rated T games like Uncharted 2 that have the same things. So shouldn't that be rated M too if it has blood and violence but also has language and suggestive themes?
I know halo is rated M for mild amounts of gore a la the Flood from halo 1-3 and halo 2 for language. Halo odst and Reach I question.
It would be nice if Halo Reach had gore. I know some of you guys think I'm talking senseless gore like gears of war. But I say that gore can emphasize the hopeless struggle of humanity against an alien onslaught that glassed Reach. You can really see the inhumanity the aliens express when they rip a spartan in half, blow up a marine with a plasma nade, show viscious burns from plasma weapons, or decap and slice in half with an energy sword . I think the gore would emphasize a real feeling of fighting for something worth saving thus making the game more imersive. Gore may also give you a bigger feeling of triumph when you kill an Elite General that has been forcing you to restart multiple times or is wiping out your allies. Gore would also lead to more 3 dimensional characters seen in films that combat feelings of ptsd (post traumatic Stress Disorder) that spartans are known to suffer from in the halo lore. I think it would also lend to the feeling of a real warzone experience that killzone 2 offered me with its atmosphere.
The gore would also be consistent with the halo lore in the expanded universe. From what little I've read of the expanded halo universe I know that the weapons in the fiction are very devastating and leave some devastating or even mortal injuries. The results they yield in the lore are nothing like in the game.
Multiplayer I'm a little iffy about though. It would be more entertaining to blow someone up, or get a gory assasination on them than teabagging a dudes body. If another studio remade reach and added gore in the multiplayer it should also be realistic as in an Anti Materiel rifle should destroy your head if you land that headshot. Seeing that the visor is like glass and the rifle ignores shielding and armor when shot in the head why not? But on the other side I would say no since the technical requirements to implement it would be costly and the amounts of lag that might occur since Reach levels are 5x the size of cod maps. And gore would just cause visual hiccups.
