So there's been some controversy about a new release Detective girl of the steam city, with the release thread being locked. Apparently the game features rape porn.
Googled it, and this seems to confirm it as well:

https://rpgmaker.fandom.com/wiki/Detective_Girl_of_the_Steam_City#Bad_End:_Trafficking

"Bad End: Trafficking
Sophie got sexually assualted or gang-rape by the gangsters and she trapped inside the case as a sex slave. It is unknown where that happens to her or she's no longer to being detective. "

I'm not going to argue whether Gog should sell such content or not, since clearly this will only result in lots of "free speech" advocates asserting their right to that kind of material. However, I think Gog should clearly mark such material, so buyers know what they're purchasing. Violent porn is clearly in a different category than some of the other 18+ games/visual novels which just feature various kinds of consensual sex.

EDIT: Link to my wishlist entry requesting such a change:
https://www.gog.com/wishlist/games/mark_games_that_contain_rape_porn

So the bad ending is promoted as a good thing, as "exciting"?
Can't be as fun as shooting people in the head or dismembering them alive.

I believe that a bad ending...is you losing, i.e. is something that happens to you that is depicted as bad. In "Prince of Persia you were cut in halp by a guillotine and/or pierced by spikes (and that meant the princess also would die in her cell for refusing the old vizier, if you happen to care especially about females).

It all depends on how exactly and in what context it is depicted. Moreover, you still can object to the scene but please keep in mind that is both drawn without any real scene or actor as a model and complete fiction. It's not a video of some tricked girl actually been raped.

That said, GoG should make it clear if something is porn, is splatter, is ...whatever can be of interest or be unpleasant to the buyer/viewer, even if that porn were somewhat romantic or mild. It's a matter of correctness ( Not of political correctness)

PS I believe the thread's been locked due to the debate becoming unbearably hot (not in a sexy way) to the point of people insulting one another. I think it's a good reason.

The game apparently also contains other scenes where the protagonist is raped (and learns to enjoy it).
Again, I'm not going to argue whether such games should be sold here, but they should be clearly marked, so one knows what one's buying.

It's quite common in hentai, actually. It's some sort of overlapping between suspension of disbelief and shock value/transgression. It's a kind of trope there, and is obviously controversial. I agree too that such cases (along imho a lot of other topics including generic porn, gore, and even a frank description of what kind of gameplay and plot genre it is)
shall be more clearly and unambiguously marked. A description *not entirely* provided by the distributor but by curators, plus a more articulate set of tags can help a lot imho. Saying 18+ is more of a diclaimer for legal purposes honestly.
Even The Witcher or Doom for DOS are 18+ (maybe not really Doom; it was made before PEGI, but it would have been 18+ if it were made after year 2000 and it's only shooting monsters)

gog shouldnt even have child rape porns

5 second generic death animation is equivalent to 10 minute rape scene?

It was an example. If suggestive content is the point, it can be very brief. Very striking or gruesome or psichologically disappointing scenes of 5 secs or less do exist. These particular iconic PoP scenes were far from the shock level of a rape, but I remember playing it at a young age: for 1989 graphic standards, there was blood on the blade, and the game still runned for a while showing you char dieing and dismembered and the trap going for a bit. There are of course longer "defeat" scenes and can even be considered a plus or have some dark comedy effect (remember "Sierra deaths"?) and disturbing content is not a matter of strict screentime. It can even happen off-screen (the infamous scene about Meryl in MGS was only told to the protagonist but is central and specifically crafted for you to feel responsible about it)

Please vote if you agree.

As it was explained, that is basically hentai. So pretty much every single hentai game on the site would be marked as violent. There's not one single hentai game on the site without rape or very aggressive sex, that's the genre. You might as well just tell people that GOG is selling hentai. People that know the genre kind of expect that content by now. It happens to male and female characters, there is no distinction. Starless as I said is an example of both female on male and female on female aggressive sexual torture and it is a very popular game in the genre along with the classic Bible Black, where magic is used to cause sexual things to happen with characters. That goes back to 95 and if you mention Bible Black in the hentai or even the anime community in general, they know what you're talking about. None of this is new for the genre, if has been that way since the 80's.

My issue is that you're asking a store to do what Steam doesn't do, which is mark the games in this way..instead of going through all this hassle, it's just easier for the site to add content filters just as Steam does to these games so you don't see the content and will not be offended by it. There's no need to mark the content as anything if you never see it when you filter out this material. I hate to say this, but even the youth of today know about hentai. It is one of last year's most popular topics on pornhub and I can assure you it wasn't only adults watching that stuff. What I'm seeing here is a culture shock. All of this is made in Japan for the most part, and their people are fine with it as long as there is a mosaic. There's mangas full of it too. Indiegala also sells this content through Mediabang and I have seen no complaints there at all.

Not everyone might know that. I certainly wouldn't have suspected it about this "detective girl in steam city" game with its cute graphics, if it hadn't been pointed out on the forum.

No, that only means that you only know a very limited range of Hentai.... Hentai by itself is a term cover all erotic / pornographic manga and anime, not only those who have violent sex. There are many different types of erotic manga / anime, some very soft, some qutesi, some aimed at women etc.

As a bonus point, the term Hentai is only used outside Japan. Within Japan they use "ero manga" or "ero anime" instead.

That's the problem. As I stated, even on my show last night - stop mistaking cartoons for kids. These are not cartoons for child consumption. They are for grown adults and have been that way since the early days of hentai localization. The cure graphics are part of the kawaii or moege style and are very common for the genre. Cute =/= Cuddly if you will.
I know that, but most of the ones here do. Most of the entire that GOG has picked up from Kagura do feature the rape stuff, it's kind of a thing with Kagura. Evenicle also had it. No, not every single game, but at least 90% and mostly the Kagura. Most of the games we get localized are this way. It's also hard for some people here to accept the cure look of the characters as they liken them to children and that becomes another problem. This is more of an outsider issue to be honest. You and I are familiar with the genre and style. These people aren't. That's why I suggested a content filter weeks ago. They act as if certain scenes are new and frightening, when they have been a part of the genre for decades. If one takes a look at the games on DLSite, they'll see what this is all about.

No, not all of it. And some of the stuff aimed at women is Kara No Shoujo which has rape and murder. I know a lot of women who love that one.

so all of these kagura games are underaged rape porn?:O holy
this is worse than i thought
i cant even imagine what happened during childhood that makes people want to buy these games
sadly abusive relatives is still a thing and many times result is deviant behavior

Hmmm... maybe GOG should stop selling violent pornography altogether?

If they can't even draw the line at this shit, what is wrong with them?
