Souta isn't actually good at talking with girls, so a friend of his introduces him to a website called Angel Navigate, where people talk about love. Souta decides to visit the website anonymously...
Common route is too short, half an hour or so, and individual routes aren't much bigger - two hours on average. After characters meet in real world, all internet dating setting goes to trash bin. Dialogues aren't interesting, so I believe I can safely condemn it as moege.
"Can you become a coach of the track and field club?" Taka gets interested in the offer. That accident ruined his hopeful school life and future.... He has been doing rehabilitation hard, so it is really a great offer. Even if his position changes, he is glad to engage in the track and field again. He decides to accept the offer with hope in mind, but various troubles happen...
The good thing is that four heroines train as a team, so other heroines do not disappear suddenly. Protagonist is serious. Each heroine has a different story and ending. But game lacks refinement, and quality is below average.

7. Hime x Hime 姫×姫（ヒメヒメ）  Etoiles
There is a famous school where rich boys and girls belong to. The school has a traditional custom that a girl called princess governs the school. The main character accidentally enters the school though he is just an average student. But he can't move to a school dormitory because of some troubles, so he starts living at Saki's, the current princess, room. Saki is selfish and he works as her tool. He doesn't like his school life at first, but he gradually gets attracted to Saki...
Princess school setting is a thick red line for me. Even assassination line is taken directly from Shield 9. Personalities are rather bright, so can be ok for those who like such setting.
Here's our young man, Yuge Fumito.
"I'll become a writer!" he vows to himself, and rides a train to the magnificent city of Tokyo!
He comes to a publishing office with a self-made novel in his hand and knocks on the door, but the world doesn't go so easy on him as to take him for real.
Fooled by a wicked bunch, he finds himself penniless and homeless.
Moreover, his vital work (still unpublished, however) would become a failure.
Despaired and rain-struck, there the young man kneels.
Then an umbrella is softly handed to him. As he looks up, his eyes meet those of a female student, worried for him--
With a few workings of fortune, the young man begins his school life at a respectable writer's.
Under the same roof with the beautiful sisters, he's running around the city with the editor girl, getting invited to a party by a British consul's daughter, followed by his childhood girl friend from his home town, getting literary advice from a cat that can speak, and so on--
The young man meets new people, gathering life experience.
Among the above, there is a piece of advice the cat had told him:
"Love, schoolboy. Fall in love, be loved, pine with love, make love the sole source for your script--"
The young man lets "love" which he had never pondered on before, take over his mind.
Will you be able to become a brilliant writer?
And will the love between you and that girl you can't stop thinking about succeed?…
Live the days of romantic emotions, and reach out for your dreams and love!

9. L.i.n.k. -Kimyou na Unmei ni Tsunagareta Monotachi no Chi to Namida no Uta-L.i.n.k. -奇妙な運命に繋がれた者達の、血と涙の謡（うた）。  SGP Software
There are witches in the world. They have special power like an old magic. But the word "witch" means "assassination" in the modern world. Witches establish their own organization and run a business to secretly assassinate people. Shion has power to "curse people dead". He receives a job offer, completes it, gets a reward and goes back home. He just repeats the same day.... But one day, he just goes home on a different route and meets a girl called Ai along the way. They become friends, but this is just a beginning of ruin.... They, however, decide to walk together to step out of their boring life...
Serious atmosphere is hurt by lack of explanation. Instead, same story is shown from different characters perspective... which still does not explain much. A lot of confusing stuff combined with low overall quality in every field.
10. Momoiro Guardian ももいろガーディアン  Alice Soft
One day, Takuma's mother says to him, "You'll be the Maou when your next birthday comes." Though he doesn't believe it at all, a girl suddenly appears in front of him to hunt him down and another girl tries to save him. These girls also transfer to his school and start living at his house...
Alice Soft H tilt is so big that I had to block their last title as nukige. In this case it's claimed to be an absurdist comedy which is of course a shallow low-price story-less opportunistic nukige. Tsundere flag is the only thing that can make someone play this game.
You start off as Kenji, a pretty ordinary kid (yes you start off as a kid) who’s visiting his aunt during the holidays with his father. There, he meets his cousin Ai, a quiet girl who is just one year younger than him. They were left together in the house so they went out to the nearby sea to play.
But because Ai was so quiet, Kenji decided to play alone in the sea while Ai looked at him from the beach. Going back home, Ai lied to her mother that they had fun together. This continued right up till the end of the summer holidays.
Feeling really guilty, Kenji decided to be more friendly towards her. The next year, he took the initiative and played with her. Another year passes by and he came over to her town for the holidays. They are already extremely good friends and look forward to each others company.
Then the bombshell was dropped. Their parents were getting married. But they were still young and didn’t really understand what was happening. The only thing they knew was that they are now siblings. Kenji now stays in the same town as Ai and lives together with her. New neighbors, new friends and new adventures await.

His company is about to go bankrupt. Raica, his childhood friend, knows it and says she will join the company, but she is actually a very clumsy girl. Will Tio be able to get through this crisis?
Let's rebuild family business and create harem - yay... Text power is weak, so there's just not enough persuasiveness or excitement.

Perverted hermaphrodite protagonist and loli magical girls make a basis for a solid story (NOT).

17. Tropical KissトロピカルKISS  Twinkle
Kaito left his hometown with a dream to be a big man. But he doesn't have any clear ideas, so he just lazily lives every day. It's no good. Kaito decides to work at a newly opened resort facility called "A LO HA". But he meets various girls he had relationships before there...
Charage with some humor. All girls are in love and fight for protagonist confessing to him at the same time. Hello, harem. Individual routes are rather normal and quality is high, so it mends prologue stupidity to an extent.
