Let's wrap this matter up, before I go off on a tangent.
Here's the thing: Sex sells. It sells porn, it sells movies, and it sells videogames. And you can hate me for saying this, but it's not all bad. There is a good kind of sexy, and there is the tactless, shallow kind. Bayonetta, for instance (see the trailer in my "On a Lighter Note" post) is a heavy sexual trip. Innuendos abound, over-the-top sexiness, partial nudity, and God knows what else will be in the final product. However, its sexuality is so rampant and silly that the game can't be taken seriously; it becomes almost parodic.
Blade and Soul is another game with scantily clad women. But notice too, that many of it's men are scantily clad. This is Hyung-Tae Kim's style. He draws in a style that pretty much ignores any anatomic accuracy, in exchange for a look or feel. Which is why his characters are either hulking and half naked, pretty and half naked, or pretty, half naked, and massively boobed. It's like he captures everything I'm writing about in one art style.
So I judge a games tact based on balance. Either make the sexuality so over-the top that it's silly, or make everyone half naked. That way, everyone wins. Or loses?
