If you guys, normal gamers hate this behavior ... I've been voicing this pragmatism/laziness for 2 years.
First, my job is 3D animation. Creating from nothing, without character generation, making nude model, rig it, etc ... till the nude model finished and ready for animation. That's a dedication, an art.
Second, compare to old games using 3D model. There's ton of them that looks so good and unique to their own style. Until Daz Studio became a thing and easily pirated. Now every model look the same.
Third, Un-certified Pevert Developer/Story Maker. They just create a 3D model an name it "MOM", get young boy name it "BOY" / "SON". And do taboo sex, and that it's, tag it Incest games.
Many many of these games are (analogy) written by 13 years old pervert boy. They just focus on sex, not the motive. I have many times called out these developer and debate them over their games lackey on story motive. While I can cornered these developers, their fans are the one who shut me down for criticize them. So these lazy developer instead getting criticized and up their quality, since the fans also 13 years old pervert gamers who only care for sex scene, they create what the demands want. F U, to that kind of fans and dev.
We all know, hentai & adult games are fiction, but that doesn't mean the human behavior in the story also unreal.
1. Incest (Mom & Son)
Ex. "Son teasing mother 3 times, showing his cock, and with little push or ransom, mom suck her son dick"
This is the kind of unreal behavior and show how lazy and low quality of story.
There's is super thick line of how a mother can love her child, from love of care, to love for sex. Our target is too make the story that the mother break this line. So we have to create a good story how the mother can go to that dark area of morality. Also, a mother has look penis before she see the child penis. Penis isn't that intrigue by woman. Man can think when we show our penis to woman, it's an instant sex appeal. THAT is LAME thinking ! . Woman not seeing our penis, they see the man's "AURA". It can be result of the man character, wealth, look and unique charm, and other things. But definitely not just because showing big penis. But we as man, DID, see woman by their look. We put aside the woman character, we see body type first.
2. All girl are slut & brainless
OMG, how I'm so done with games that use this kind of plot/idea. (Majority of games use this thinking)
Hell no ! ... Yes, woman can be "subdued" but each woman has different integrity level. Look how many games, when we introduced to their character, they already use slutty clothes !!! . This is how one don't have intellectual to create a decent story.
3. Story, creativity & motivation are brainless.
As above comment, they are just join the band wagon. Use Daz, use rape/mind control/incest story plot, create sex scene ... release.
These developer should read many drama books. When you read those fiction drama books, you can literally add some sex scene to it and it would be good adult story. Creating own good story is hard, so do grab from those drama books.
If you think LOP games are good, it's not. Majority of those games are also have bad written story. They too use either of Daz Studio or something similar, and the story also weak.
There still so many things you can criticized, but some can be compromise, such as ...
4. English 101
Come one guys, some non-English native people can understand/learning English so fast and create a good sentence, but some are don't. Me include, hehehe ... So it can be fix later on.
Creating games is not an easy task. You have to dwell with thousand of script lines, consume thousand hour to do it right. 1 wrong script can produce many bugs. So be compromise that 1 wrong English 101 is nothing compare to it. In this world, it's 1:20 between native English speaker and the rest of the world language. And from that comparison, it's 1:100 for non-English native people can understand English perfectly. Those Russian's developers are tired when criticized not able generate good English speech. So they are retaliate by not making English version at all, because if they do, you guys who master in English degree are try to be a GOD by pointing this and that. Then that's their answer, try to be good in Russian 101 ... can you do it folks ? Think again.
