I wonder if the 14 graphics engine can do something like this.

Reason for an ethics department is because buyers in the west tend to be offended by things the most.

China would like to chime in here perhaps? I have never heard of a game company completely reworking graphics and stories cause they want to sell in the American or European market. It may have happened once or twice, but again, I think everything in between Japan and Europe would likely be more the culprit of any ethics dept.

Twitter trolls supported by army of twitter bots.
Western players does not care for silly things like that.

Twitter is full of bots and is ruining todays public social interactions, people should learn to stop caring for it.

That's a lie most West would have no problems with this. Just look at Conan Exiles. Also look at all the RP players there is.

CookiesNCream is correct that the Western Market is a lot more sensitive about certain things than Japan is.

AnimaAnimus is also correct that China tends to be even more sensitive though incorrect in stating that game developers don't have to change things for the NA and EU markets. It's done a lot more often than people think.

The culprit isn't the players and what players will accept. It's the ratings board and retailers. A lot of retailers won't carry products that aren't approved for use by at least teens by the ratings boards. Each country's ratings boards has their own list of hang ups that will cause them to put a mature rating on a game instead of a teen rating.

YoshiP even went into a far amount of detail during an interview about some of the things they would like to do in cinematics and in game but can't because of the NA and EU ratings boards.

As for the OP's request, it's possible for SE to do. The question is how they would use the sheer appearance in gear models and if the ratings boards of any countries would have issues with it. It may not be a fight worth SE's time to battle since having such sheer appearances isn't necessary to the game.

Would you be happy if new content and features were delayed 3 months because SE tried to get something past the ratings boards and then had to redo everything when it didn't? Probably not. Better for them to take a more conservative approach they know the ratings boards will accept so they aren't forced to redo months of work at the last minute.
