I've covered this topic in a some of my blogs. This is a problem we have had in every form of art or entertainment. it seems the moment mankind invents something or an art form we have found to use it in pornography or make pornography with it.
Now sensuality and nudity have been done in a tasteful ways before, but at the moment we have seen so much that the suply is greater then then demand. We see so much we are now desensitized, to this type of content, so we have to go bigger and more blatant.
However now its getting to the point where it is too much and all but the horniest of us are getting annoyed by this. I can appreciated beauty when I see it, but but not like this.
Since Yuna is overplayed in this area, I'll go for DMC's lady.
DMC3: While the school girl outfit and the occasional shown mid-drift is there for fetish fuel, and she is an attractive young girl. However I saw her as more of a strong young woman, who was willing to play rough with the big boys and kick ass with the best of them.
Go to number 4 and we have a girl in short shorts that are so small that they are practicable little boy undies, and apparently nothing underneath that shirt that is already halfway done bursting apart. While her chest hangs more realistic then most video game females, she has gone from a key plot device and major character, to only being there for a few brief moments for the a minor plot device and some pans at her cleavage and butt.
That is what we got.
Plus some girls are not helping things much either
