I would also really like to know why this feature is in the game as it is now. To be honest, I've been skeptical about the nudity in this game when I heard it was a 100% first person game. The reason for that is that sex is first person is way more explicit than cut-scene sex. Geralt for instance sometimes goes down on the girls he has sex with. If the camera remains in first person, you have more or less an entire screen filled with genitalia. I just assumed they would just lock the camera and oral sex would be a big no-no for CP2077.
When I read CP2077 would allow the player to customize their genitalia I thought it might be different and also why not? Why shouldn't a game that allows you to blow people's brains out also allow you to see genitalia? Furthermore, CDPR kept pushing the idea they were making adult games with adult content. (And to make one thing also clear: I wouldn't have gone the full-screen genitalia route myself, but I would have shown more nudity.) There was also the gameplay demo one (or two?) E3's ago where this naked chick was lying in a bathtub full of ice and beside her was another naked dude that reinforced my opinion.
Then there was this allow nudity filter which and the genitalia customisation at the start of the game which seemed to point towards a game that contained full-frontal nudity. But now it is only in the inventory screen?
To be honest, I doubt that this was planned from the start. Rather, I believe this was a decision forced upon the developers to make sure the game's rating would not be to high and this decision was probably made after they had already announced the genitalia customisation on the character screen. If they hadn't announced it, it would have been removed from the game.
Also, I'm not mad at CDPR and I would have still purchased the game, because it is great and it is not about nudity and sex after all. But I am a little disappointed because I think the game industry in general has no issue with an abundance of violence, but shuns sex.
Well, I just wanted to get this off my chest. Have a nice evening!
