These are my advice for the developer, since I like the 3D art, without going into the story
Hairy Armpits/Pubic, Skat, etc are Niche
If u have dedicated Patrons who actually pay u for these tastes, then by all means, but do not expect much from mass audiences. If u decided to add these & want to cater to Mass Audiences too, make sure they are optional, to sell more copies of ur game or acquire more support for ur project.
MILFs Genre
Men who play these games, generally want to go back in time & tap all the MILFs who they have had eyes on, as youngsters. MILFs as Moms, Grand moms, Older Sisters, Aunts, Neighbours, Friend's moms, Older Sister's Friend's, Bully's Mom, Teachers, so on. This is not a Freudian fantasy for their own moms, no, its a instinctual hunger for Well Developed Fertile women. This is a natural instinct for normal men in ur mass audience. Men, no matter the age, are hard wired to compete for the most well developed women, like ur model above.
Return to Young Genre
Again, Men want to go back to being a boy in puberty, with no care in the world & do MILFs, they lusted for when young. This is normal, to yearn & fantasize on our MILF crushes that we have had in the past, as boys. We cannot all be Jupiter Macron of France, but we can fantasize about that MILF Teacher that we so wanted to plough as a boy. Again, this is just that instinct for well developed women, that kicks in, for men, with the added fantasy of being young, care free, full of energy & looking forward to so much in life (with MILFs). These fantasies help men handle their regrets in life as adults, since life may not have turned the way they thought as boys. These are normal fantasies of men in ur mass audience for going back & being with that well developed woman in their fertile prime, the MILF.
Men want to Hunt, not be fed
This is a must for the Men in Mass Audience. Most men are hard wired to hunt for their mate. You need to add carrots & sticks. Traps & Ladders. You must tease them mad & please them for their effort. Set up must be good & pay off must be good. Getting into the pants of the women u create, must not be easy or difficult. It must be done just right, to not waste the time of men in ur mass audience.
Plot & Character Development
You need a writer, while the artist does the 3D art. The Plot, Story & Character development must lay the foundation for sex. Sex is the pay off & how you do it, depends on you. Humour, thrills, suspense will spice things up for sex. But the most important thing is to inspire men to hunt for the women, giving these women assets that would motivate these players to spend both money & time on ur game
Sex needs to be Natural
You need make love between the Player Avatar & NPCs. Design the sex scenes as natural & make them flow well, like a man n women makin love.
Most Women Players need to be chased & seduced (in case u creating game for female players too)
Men u create for women, need personality, ability to seduce the female players who play ur games. They must talk n talk. They must induce excitement & make sure the women players enjoy their company. It is not the size that matters, its the story of the guy & his personality that matters, when he does her. These games require a lot of words. Some times, u can give an orgasm to women, just by words. No need for the Male characters in game to touch her Avatar in game. You do this with story plot & character development, set ups n pay offs. Some parts of this applies to men players too.
Mass Audiences & Niche Audiences
Know the needs of the Masses v/s the needs of the Niches players. Make a balance between ploughin the mass players for money & the niche players for money. They best option is to plough both, by making niche things optional
Millennial / Zoomer Gender Things, Post 2010
Cater to this, only IF YOU GET PAID. Do not waste ur time with this if the game is being made with ur own pockets. Anything about Gender or Words from the West, Post 2010 is lame nonsense. Best ignored, because the mass audience will ignore ur hard work. You will not make any money catering to this nonsense, that's coming down from the Western Elite Cabals Above, as these Elites have lost touch with humanity, long ago, due to the vast fortunes they have. Their vast assets cuts these Elites off from ordinary people & these elites in their loneliness above, have developed mental problems concerning flu, changin weather, gender & population of the ordinary people below them. They see us as Serfs they must control & themselves as Gods. Forget about this, if u have not been paid.
There is a Market, if u can balance Niche Elements like Hairy pits, making them optional, while also milking the mass audience.
These are my advice for the developer, since u asked. Hope this helps.
