I like Ota Guchi bc they nail what id call a "breezy" tone. It really gets that "slice of life sexcom", with just enough effort is put into the world to feel lively. It honestly reminds me of a Yakuza game, specifically that its about a protagonist that sticks out somehow, wandering around a densely packed burg full of goofy characters (some recurring some one-off). This is all against a main plot thats generally stupid and goofy and trite in a fun way. Only instead of starring an ex criminal, its a girl who learns to be slutty.
The Muchi games had the older sister try to get truant classmates back to school and developed a slutty side depending on your actions. There was also B and C plots about a female friend becoming a sex slave and the mom "paying" for the mischief of her tomboy daughter.
The Yutaka game had a supernatural element where a jealous classmate dug up an evil spirit that caused schenanigans. There was time travel and curses and stuff.
I love em bc its that extra layer of silliness thats entertaining. Like watching a mediocre anime plot get derailed by porn.
