I don't think it has to 'resort' to that kind of thing, God of War 1 and 2 were still good despite a very small sex scene.
Honestly, it's already a Mature game so it doesn't really bother me at all. I get more annoyed when a game that's rated M is more like a Teen game and it feels like the thing that's making it an M rated game is merely an excess of blood that isn't even needed.
However, I do agree in that I think it's annoying that I have to make sure other people aren't around (when I'm at home) when I want to play it because of the female breasts and nipples.
