Does anyone know what this game's genre is called in Japan and/or here? I think this game specifically has similar playstyle to the category 'Simulation' on dlsite, but what I am looking for is a categorization on the tropes utilized in this game, a categorization which would include the following games:
Summertime Saga
The Twist
Town of Passion
Milfy City
Bone Manor
Harem Collector
Zombie Retreat
Lust Epidemic
The tropes seem to basically amount to a male protagonist trying to fuck a small set of females, which is kept small to have more sexually depraved and advanced scenes with these women. You also basically go on fetch quests, which gets you small bonus scenes or advances the sex between your characters, and helps encourage the player with achievements like RPG games basically do. It's not really harem because that is more of its sex content genre. It might be sex rpg?
It honestly depends on the website.
On Krublog they call it "Dating, Cohabitation and like u said, Simulation". On here incest, corruption, male protaganist and no NTR tag is probably the way to go.
I would say your best best is the tag incest...and not doubt this at all, the barrier means effort has to be made to break through it as part of the plot. If you're looking for more like this there's my secret summer, a zombie's life, last hope, Imouto! Life ~Monochrome, teaching feeling...and I can't think of more but there's obviously more. The majority of japanese vns are heavy in femdom, ntr(watching the girl you wanted to boink get boinked..this gets argued about a lot but it isn't that complex...its cuckoldry), and monster rape. If you are planning to go off f95zone looking for some magic miracle porn...it doesn't exist..people always translate the ones that align more with our western wants for us.
