I feel parts of this thread are trying to equate the situation in 2005 with the situation in 2015, when they're actually very different.
In ~2005, we were having debates around topics like Hot Coffee, Jack Thompson/Leland Ye, and Mass Effect, where the question was clearly "Why is there sex in these toys for children!!!"
That era has long since passed in the West and having nudity and sex in games is a completely non-issue on that basis.
For example, let's take The Witcher 3. It's a game where you can have graphic, full nudity sex scenes, can sleep with multiple women, and can even sleep with multiple women at the same time. There was no real controversy around this. If you look at the only "sexy thing" controversy the game actually had, it was that people felt Ciri's heels were impractical for Witcher fighting.
As you may notice from this, the debate in the West in 2015 revolves around the context of sexuality rather than sexuality itself.
This is why the whole Dead or Alive Xtreme 3 scenario is ridiculous. Feel free to go through this 365 post thread entitled "
Dead or Alive Xtreme 3 (PS4/Vita) - Debut Gameplay Teaser Trailer & Screenshots" and point out all the times people complain about the game. If you don't want do, I've already done so and can tell you there are none. Someone mentioned that there was one other lengthy thread where they saw a couple of complaints, but we're looking at a very low ratio of complaints happening here if at all. The reason is that the context of the game is clearly to gawk at women in swimsuits who are at the beach, so there's nothing about mostly naked women that actually seems out of place here.
Now let's move on to a character who generated a lot of controversy: Cindy from Final Fantasy XV. So the premise of Final Fantasy XV is that you're going on a brotastic road trip on your way to an arranged marriage.
Let's imagine that FF15 was a modern WRPG instead and the developers wanted her to be a sexual character. When you first meet her, she'd likely be fully dressed, maybe with her regular mechanic's jumpsuit somewhat unzipped. You'd then be able to flirt with her, go on a date to a nearby restaurant, and then have sex with her. In the sex scene, she'd wander out in the outfit she has now and make some terrible pun about how "I'm dressed to fix a different kind of problem today." and then she'd end up stripping off the top and you'd see boobs and an actual sex scene. This is the type of thing that would go unnoticed in 2015, because it's fully contextualized and generally expected.
However, this is a T-rated Japanese game where they actually view their audience as potentially having lots of children, so instead of putting that in or even having implied sex scenes when a guy is on his way to get married, we just have her sitting there mostly naked as part of her regular work attire. There doesn't appear to be any attempt to actually contextualize this either beyond the game just going "LOOK!! BOOBS!!!". When Tabata was asked about her character, it's not like he sat down and went "Well we're making a T-rated game, but it's in the style of R-rated road trip movies, and thus we're attempting to get into that raunchy nature while still keeping it appropriate for younger teens. As such, Cid runs a series of mechanics shops called 'Tube Lube' that are essentially like Hooters. This is why Cindy is dressed this way. It will be clear in the full game." Instead, his answer was basically "Our artists wanted to make a hot chick and I didn't want to bother coming up with a reason for it."
The defense of nudity/sexuality in the 2005 era and the complaints about arbitrarily sexualized outfits in the 2015 era are actually coming from the same place. It's about people not wanting to be treated like children.
