Personally I think it would make sense for sex to be integrated into video games in a tasteful manner. I have my doubts that it will ever happen (its barely happened in movies). I realize this is a bit tangential to the OP.
The west doesnt see adult video games as anything legitimate. My guess is that they are mostly pictures or videos with game elements tacked on. (I dont have much experience with porn games). In japan most of the games are more what are more like chose your own adventures with sex scenes (I have at least looked at H-games).
Porn is in japan is an interesting subject in japan, without making a huge wall of text, it would make for an interesting discussion as long as handled maturely, not tentacles LOL. Anyways porn is visible and can be openly browsed at various open places but people mostly ignore it.
That is a vast over simplication but thats another discussion.
Yes I am a fan of the Playstation 3, but I am an even bigger fan of intelligent and rational dialog. (If you are up for an intelligent exchange of ideas, you are more than welcome to add me as a friend)
PLAYSTATION®3 is the future......NOW.......B_E_L_I_E_V_E
