Game is localized and has English reviews.
Kyoko is a young woman who does some counseling in a high school; she must talk to people, listen to their problems, and try to solve them. Naturally, this being a hentai game, the problems are usually restricted to sexual fetishes, and the counseling often consists of helping the patients in such ways that new problems of a similar kind might arise...
Quite a loose ero-centered story about counseling on sex problems.

3. "Blood line" is about a an adult store owner Eleanor who supplies space ships with sex dolls. She learns about a suspicious disappearance of a space ship that is rumored to be hijacked by a terrorist group. It's a multi-site adventure that shows another point of view after initial playthrough.
Stories are set in some desolate future and quite elaborately done. It might be the peak of multiple stories genre, but whatever complicated prelude is, it inevitably leads to multiple H events.
Unlike the sequels that follows you take on the role of Kenta, a high school student trapped by Isaku, the eldest brother of the Itou Family on the fourth floor of an abandoned school building together with fellow classmates and a teacher.
The main objective of the game is to have the player and his companions escape from a locked school building, and to avoid having your companions captured by Isaku.
The only way out is through a stairwell, the doors of which are locked on every floor. The player must search the rooms on each floor for clues and items that will lead him to locate the keys that will open the stairwell doors and allow him to descend to the next level and ultimately to a final confrontation with Isaku himself.
Famous rapist series of Elf, but this first game has an ordinary high school student as protagonist, so it can be enjoyed. There is one English review. First things first: this game has an amazing point and click system, probably ideal one. There are items to pick up at school, but if misuse some needed item, you won't be able to get a happy ending, cruel as that. There are few VNs with escape as main theme, so it's a nice treat. The graphics of Elf here are in its blossom and it's especially cool that the most attractive character is Kumiko-sensei and not those multiple girls. Game basically has no flaws and manages to have all the elements in sync, so it's a masterpiece, just not for everyone.
The year is 2023, and you play the role of Hajime Kudo, a young man who has just finished his studies at Jiyugaoka University.

Naturally, you're intrigued, and make it a point to spend your vacation time at May Club hoping to meet the woman of your dreams before starting your new life.
One of the well known old dating sims. Has many English reviews.
8. Moratorium モラトリアム  Gloria
Your father remarries and you end up living together with three new grown-up sisters.
This work has some gag situations in addition to H events. It can sometimes be seen as a unique comic book and it's easy to read.

Kuniharu must explore the mall and gather information by talking to shop managers and staff, most of which are attractive young women who may not be what they seem at first glance.
An ADV that incorporates time system. Every map movement takes some time. Suspense story about missing people that turns out to be about organs shipment. Even if you find the criminal, it's only the peak of the iceberg and the puppeteer remains unknown. Graphics is great. There are multiple endings and some of them are quite cheerful in contrast with the dark suspense mood of the game. Of course, there are a lot of bad endings as well, so a guide is almost a necessity in such time driven game. Very original game worthy of masterpiece title, but the modern remake of the game makes old version obsolete.
Girls school recently started to adopt male students. There's an old urban legend about a ghost called "young lady" at school and three ghost study club members are set to investigate it.
It's lesbian comedy. And it's more lesbian than a comedy. It's more or less fun through the middle, but don't expect to see any kind of story development here. Yet another bakage with emphasis on H-scenes.
Trigger 2 consists of three unrelated stories. The protagonist of the first one is Kerberos, the mythical guardian hellhound.

The Earth is under assault by aliens called beasts. They choose this green land as their breeding grounds. But in the Universe there is also an organization that opposes these beasts, and its agents are instantly sent to the Earth. A new round of confrontation starts now.
It's basically an anime presented as a game. Great move, but difficult to justify such medium while anime presents a much more comfortable approach.
