Sony and MS do not directly rate the games. This has only parts to do with Sony/MS and Funcom, and more to do with the ratings board. It is how often, how in your face, how gratuitous it is, and whether is really needed to tell the story–violence, the “slaving” of thralls and objectification of the barbie doll physique of the women that combine to make the game beyond what the rating board certifies as M. For Conan, it is not only the nudity causing the rating.
