Because being that it is graphically advanced to a game like COD2, it shows that...interesting stuff, in more detail; not like a red splatter in COD2, but the content really is QUITE minor. I honestly think there are much worse M games out there. I mean they slapped an M-rating on Oblivion at the last second before release, most likely because of the alcohol content, which is minor as well.
It seems that game companies are slapping M-ratings on games that show a little blood, and say a**. Yet we have movie raters who give a raunchy movie a PG-13 rating, even though is shows partial nudity, includes alcohol content, AND contains minor foul language (just like Halo 3, minus the partial nudity).
It's really insane when you think about it
