1. Chaos Blood カオスブラッド  Ange
Komiya Soma is leading a casual university life, but one night he gets involved into strange case. A student girl stood naked on the rooftop, repeating meaningless words and eventually starting to pee.
It was only the first of a series of incidents to arise in the future...
Minor work. Ugly character design. Story is tilt to weird fetishes and the synopsis is set just to show them. There are three routes, each featuring two different girls.
The story behind Collector is that the main character has attended a well-reputed high school for a long time. Yet, the main character was disgust by their strict school policy and the boredom in the school. He wanted something interesting besides attending school and go home. And thus, the main character participated in a strange club that his friend has introduced to him. In this club, the main goal is to seduce girls to the clubhouse and rape them! And guess what? The main character is assigned as the person who will be responsible to bring the girls to the clubhouse. From here on, your quest of hunting down girls begins.
There is an English review.

He has views for six pretty women around, but at the same time he needs to solve hospital's new problem - principal's wife caused a riot and a big contract was cancelled. Moreover coworker pharmacist is behaving suspiciously. Hero will need to solve all the problems.
The choice of a girl depends on the type of work chosen every day. In the dialogue there are options to raise and lover favorability.
4. Kinjirareta Asobi 禁じられた遊び  Vision
Protagonist receives a funny flier from a woman with butterfly glasses on the way back from the company. It advertises a relaxing machine that makes sexual dreams true. He pays a visit to the place and meets another woman with butterfly glasses...
Ero-centered game without text, voice only. Lots of animation as always with Vision.
5. Kokuhaku 告白  Guilty
Three high school girls confess their problems to main character who works as a counselor. He will need to find the right approach to each of them.
Girls have very difficult sexual problems relating to different fetishes. And it's impossible to get to true endings till the normal endings for each girl is got. A very exhausting game.
6. Megami no Hohoemi 女神の微笑み  Palette (old)
Humans are extinct, only computer "CZ 25" with a will keeps existing. He strongly wished to see his creator and other human beings, and one day the goddess of time comes before him. She decides to change the past in order to fulfill his wish.
Modern time. Takuya Saito fell ill on the day of exams and now he is a ronin. One day Takuya is inspired by old friend Hiroyuki to become a high school graduate. What fate awaits Takuya?
Multi-ending ADV. There are five girls to clear and story develops by moving around and triggering events. There are several chapters with the cutest girl in the final chapter. Story development is unnatural, same as goddess of time part looks irrelevant. There is no hint that with some ending future was going to change. Game feels incomplete.
7. NyanNyan Dream にゃんにゃんドリーム  Misty
An old main is travelling around secluded locations to pick up little girls.
Stupid loli game, and it's not even nanpa, just H.
9. Nails ~Beginning of Your Heart Beat~  Jam
People and nail people share the same continent and are in constant struggle against each other. At some point a relative peace has been settled and both populations continued to coexist in several smaller nations.
The stage is Altair Kingdom.
Jam Rock is a famous swordsman. One day on the way home from the swordsmen dojo, he helped a girl chased by suspicious men. She only remembered here name - Minwi. She turned out to be a shrine maid of Theinhad Temple and her memory was sealed for some reason. Jam Rock decided to take her to the Temple of Zainhad, but he was declared as Minwi kidnapper.
Two people passed through the security net and reached the Temple of Zainhad. However, Minnie could not remember anything. That night Minwi was kidnapped by the nail people with a probable aim to bring her as sacrifice to gods.
Jam Rock's rescue adventure is only beginning now.
Dungeon crawl RPG or maybe SIM with map travel because there are no levels or stats. Changing the destination map changes characters that will become friends. Party characters have favorability scale and it rises whenever they are praised. There are 8 girls to clear and 23 endings overall. Battle is turn-based command selection. Controls is mouse only and you need to choose action, then target, then confirm, so three mouse actions for each character in each turn. There are random encounters happening all the time. So it's actually a masterpiece level game.
10. Reversible Karte RK リバーシブルカルテ RK  Black Package
A young psychiatrist, Kyogoku Kazuya looks over patients at the prestigious Psychiatric Ward every day. From the day when his girlfriend was killed in front of him, strange cases of women being insulted by patients started to happen in the hospital. What causes those incidents?
ADV with favorability of heroines depending on the number of hitting their flags. The routes aren't really connected and there is no single theme - just loosely placed individual stories. It's not a dark themed game, but rather a charage in a weird setting.
11. Toriko 2 虜2  D.O.
A woman comes to main character as a tutor. As soon as she recognizes a sadist in protagonist, she requests to train a strange girl Rikako as a slave, as well as her two sisters. This isolated mountain cottage becomes a territory of domination and obedience.
Well, there is more articulate synopsis, but who cares. It still will be an insulting training SIM. Main character is different this time. It's reported that sequel became more complex and sophisticated, but I'm not going to check that.
12. Xtasy  Dollhouse
Yusuke Kubota tries to give a birthday present to his childhood friend Hikaru and lassmate Miyuki. When he was approaching, both girls disappeared and then he himself was also teleported to a mysterious island. With the two girls he needs to find the clue about the shining stone that teleported them and return home.
It's essentially an RPG. There are even enemies to beat as well as parameters to grow. Movement has to be done with a mouse. Message autoplay can be turned on, but with no speed regulation. There's no recollection mode. So it's an exploration game with not very comfortable system and mediocre graphics (even though CG are ok).
The story follows a young girl named Amasawa Ikumi who follows the recent death of her mother to an organization known as FARGO. Ikumi joins FARGO and uncovers their disturbing nature of harnessing psychic abilities through torture.
Game is localized and has many English reviews.
14. Gen'ei Choukyou Club 幻影調教倶楽部  J-Box
Hero who is given name Ryu is invited to join private videophone club by his school teacher. The purpose of this club called "Snake Pit" is to gather people with abnormal sexual preferences and share experiences.
Nothing I can enjoy. Just phone talks with H.

16. Kemono no Sumu Kousha 獣の棲む校舎 
Ikuro Makita is a recently transferred professor at girls' high school. He gets a request from the director to investigate the circumstances of his son death that's reported to be a suicide.
You need to choose various places at school during day and sometimes night and that passes time. But there's a limited amount of time given, so wandering aimlessly inevitably leads to game over. The only review around says that the fame freezes at the second part of the game, so maybe we'll know of the exciting story from the game's sequel.
Yakushiji Shion is the eldest son from the clan punishes bad people. But after he assassinated Empire's shadow Kurobe Akiyoushi, it is regarded as a rebellion against the Empire. He gathers the clan and moves towards the North. Every day they are attacked by pursuers. At the same time he is chased by the girl Hiramatsu Yae who fell in love with Shion.
Wow. Just wow. A serious samurai story somewhere in Edo period... Hero is too serious so it's others that fill in the gaps with everyday life scenes gags. Just imagine warriors talking about strange things with serious face, soft kind of humor. Hero literally has 30 lines in the beginning and hardly 100 lines by the end of the game, his presence is not felt at all. There aren't even his thoughts. Game has brilliant vivid and very beautiful CG, lots of cool enemies and gore. Characters are very likable as well. The game is not without the faults. The speechless protagonists is a questionable move. There's an influx of events by the end of the game and abrupt ending. There are a lot of women caught up in between the warring sides... well, it might be an advantage, actually. But I consider this game a masterpiece. In 1997 I only expected entertainment stories. Or maybe I just love samurai stories too much.
18. Mugen 夢限  Trush
Dream control system is invented which allows to travel to artificially created dreams. At first it was used only in medical treatment, but since 1999 became wide spread for stress relief. You are an operator who controls such machine. You need to choose your customer and lead him through the dream so that they like it.
Three customers, several types of dreams which somehow eventually end with a H scene.
19. Namida ~Ryuusei no Saddle~ 涙 ～流星のサドル～  Zero
Aizaki Shinobi is hero's first love. Her mood has dropped as of late and she started to avoid hero. He needs to get to know what's happening to his dear friend.
A really trashy game. There are only four locations to move around and that constantly triggers new girls appearance. Talk to them twice in a favorable way and they invite to spend a night together. It's nice that the game does not really end with that and you can break up with any girl after. Aizaki is the most difficult to capture. There are couple mingames at hero's room, but overall I got a really negative impression, probably because awaited a serious game.
20. Shinsetsu Kamiya Ukyou ~Untrue~ 真説 神谷右京 ～Untrue～  Altacia
Events take place between those happening in Ivory Tower and Missing Link. There is no detective story this time. Instead, there is a story of human relations. The client is a girl who had a relative stabbed in the heart. That's the fact that can can no longer be divided between falsehood and truth... "Untrue".
The heroine changed from the Missing Link, but has the same type of mind. The work is more about portrayal of a complex person's feelings and Ukyou ability to foresee the results of every minor action to the future. The work is based on contrast with the other vomules of the series, but almost all of Ukyou visual novels are very difficult to find to make comparisons.
