I think you should tell her that it's just meant to portray the culture and society of the Greek culture. Then she'll understand that the game was after realism and not baseless objectification. She will understand. You may want to practice your speech in a mirror. And for maximum effectiveness, you should dress up as a Greek warrior while giving your speech, all to help immerse her into the culture.
Or you could buy a VIta to play GoS on your handheld so she won't see you when you play it. And while you're at it, buy me a Vita too since I came up with the idea.
If those options can't work, then there's only one option left: stoop down to her level. Steal something equally important of hers until she gives you your game back. Can she take what she dishes out? There's only one way to find out.
