I see people writing about the ESRB and the M17 rating etc..
Please keep in mind that Cyberpunk was released all over the world and that many countries have completely different standards.
Nipples, even full frontal nudity aren't a reason for censorship at all in Germany, as long as we are not talking about actually hardcore porn scenes in the game (and I mean hardcore, not softcore), it wouldn't affect the rating.
The philosophy behind that is that the human body is a natural thing and not something to be ashamed of and hide. We don't run around naked, but we don't blow a fuse if we see tits and arses on a screen.
Even graphic sex scenes would be fine, IF they were an integral part of the storyline, like fe. with a romance partner you pursue OR if it shows the way the world of Cyberpunk works.
Violence is a far more important reason for censorship in games in Germany.
I can't speak for all European countries, but I know that many are way more open to nakedness and sexual acts as America is in regards to laws.
So that being said, obviously all the logic behind the reason for censorship on CDPRs side won't apply to any of those countries with different standards.
I also want to point out that we have at least one statement from CDPR saying that the removal of nudity was intentional and that not only pertains to the player character, but also to the game world in general.
So rest assured IT IS NOT A BUG, IT IS AN INTENTIONAL CHANGE IN HOW THE GAME LOOKS. I've played before the patch and tried some of the places I saw nudity, where now is none, like in that first mission with the body in the bath tub.
You could argue that as buggy as the game was, it was actually the bug that there was nudity in it, but then that would go against everything CDPR said about the game before release AND it would be weird that it isn't mentioned in any patch notes.
Let me also point out that I'm not up in arms due to the removal of nudity, it is just one of many, many things about the game and the state it is in that I find incredibly disappointing.
