I kind of expected this, to be honest. I mean, it's a game about sexuality. If they DIDN'T have a topless something-or-other, it'd be weird.
I mean, c'mon. God of War had topless women, and you could do it with them. Other Atlus games have had topless demons, too; the Priestess boss in Persona 3 was practically naked (though I don't know if that really counts because it had letters on its boobs in place of nipples).
I don't know if I should pre-order it, though. I'm currently 15 years old, though mentally mature enough to handle this kind of thing. However, due to my age, I need my parents to go out to get it. The box art may leave a bad impression upon them, as the PS3 version (which I would need to get) has Vincent falling into Catherine's cleavage. What could I say to them to convince them to help me procure a copy...?
