Draculius is VN of the Month. There are several other games with high scores, but I'm not ready to vouch for any of them.
1. Minami no Shima ni Furu Yuki 南の島に降る雪  M ni Aqua Endless blue sky and the shining sun.... There is a small southern island. Ryo and Kanae are childhood friends, who have grown up on the island. They are like brother and sister, but Ryo gradually starts to love Kanae. One day, he tells her that he loves her. But she says, "I'm leaving this island after graduating high school, and never coming back." When he is depressed, he meets a beautiful girl, Saina. According to her, she is a legendary princess of the island. She asks him to get back the special coral to break the seal. He is skeptical at first, but she tells him that she will make his wish come true, if he breaks her seal. He finally accepts it because he doesn't want to separate from Kanae.... When he wakes up, he finds himself lying in front of a small shrine. It seems nothing has changed.... It must have been a dream.... But he finds her kissmark on his index finger....
It is a story of searching for five legendary corals and getting in love with heroine on the way. So it's a straight road with just one heroine, and other only sub-heroines. There are lines that indicate cut sub-heroine endings and twists like betrayal, but it all is scrapped, so game feels cut abruptly. Game has additional elements like quiz game, roulette mini-games and rpg-style combat.
2. Tokidoki Seiten o Miagete... ときどき晴天を見上げて…  Sots Main character lives in the small town happily. But father remarries bringing step-mother and sister-in-law to the family. Soon both parents get into a traffic accident and die. The children decide to live together as a family and keep positive attitude.
Each heroine in this game has a broken family. First half is very tiresome with cheap drama and noticing signs of affection, but in the second half a new problem arises, so it gets much more lively.
3. Narcissu Side 2nd  Stage-nana 123456 Narcissu: Side 2nd's plot revolves around Setsumi, the heroine from the original visual novel, and the people and circumstances that formed her into the character presented in the first game. She will share the limelight with new characters, including Himeko, Yuka and Chihiro.
There are English reviews.
4. Minna Daisuki Kozukuri Banchou みんな大好き子づくりばんちょう  Anastasia 1234 To counter the declining number of childbirths, government decides to activate a plan. All schools across the country will enter contests against each other. The losing school will be shut down and its students will enter the service of the winners. Thus re-igniting the spirits of the lost young generation and hopefully producing healthy couples capable of childbirth again.
The protagonist realizes that this is his chance to realize his dreams and makes a grand plan. First he "acquires" the help of the goddess of fertility, allowing his children to grow up in weeks instead of years. Then he starts leading the fight against other schools and "collecting" girls to grant him superior children on the battles to come... Gameplay is divided into two modes; Global mode plays like an adventure game where you talk, date and have sex with your followers. There is a minigame to make babies and also the simulation part is here as well in which you configure your troops and select which school to attack next. Arcade mode is where you lead the contests and fighting against rival schools. Leading your hero, who doesn't have any special powers at the start and making yourself a team with the mothers and children, who actually grant bonuses to mothers and special powers to you.
Game is localized and has English reviews.
5. Draculius ドラクリウス  Meromero Cute 1234567 Draculius begins when Ogishima Jun, the male protagonist, suddenly finds himself face to face with a childlike maid who introduces herself as Elshlant D. Annoyance. The encounter quickly brings two monumental facts to life: the first is unequivocal proof that vampires exist; the second is revelation of Jun being the sole heir of a royal linage that rules over them. Years ago, Id Demon Brandle – Jun’s vampiric father and would be future emperor – ran from his aristocratic duties to hide among the humans, eventually falling in love with a Shinto priestess named Ogishima Yukari. For reasons unknown, Jun’s father abandoned his mother during pregnancy, and upon this act, Yukari placed a magic seal on her unborn child, locking away the infant’s supernatural abilities. Following the tragic death of his mother four years earlier, the spell has been slowly unraveling, awakening Jun’s latent powers and allowing the vampire nation to determine his location and deliver an ultimatum: Jun would be allowed to continue his existence and assume the mantle of command over his people, but only under the guidelines of three conditions. Condition One: He would be placed under the watch of Elshlant D. Annoyance, serving as his evaluator and mentor in the ways of the vampire. Condition Two: The newly awaken Nosferatu would need to perform a deed that proved him worthy of the inheritance. Condition Three: He would take a bride from one of the noble families to ensure the continued survival of the royal bloodline. As one can imagine, Jun is quite taken aback by all this.
It quickly becomes apparent to Jun, that the life of a vampire is far more perilous than he could possibly imagine. As he learns that many of the legends concerning the powers and weaknesses of Nosferatu are outlandishly erroneous – mostly due in part to the vampires themselves spreading such fictional myths – the young noble is forced to completely reevaluate his own existence while needing the assistance of an experienced vampire in the process. Were the difficulties of self discovery not challenging enough, Jun inevitably finds himself caught within a deadly web of intrigue thanks to the machinations of rebellious factions within vampire society. It also becomes clear that humanity is not entirely ignorant of the supernatural world that hides from them, and agents of an ancient powerful organization dedicated to the extermination of “hellspawn abominations” violently pursue his destruction. These factors make it imperative for Jun to maintain as low a profile as possible: for his own safety and innocent human friends. Unfortunately, keeping a low profile is not something his enemies are going to allow. Then there’s the whole matter of marriage…
There are many English reviews, but it does not stop me from adding mine.
6. Isamashii Chibi no Iinazuke いさましいちびの許婚  Studio Kagura Nagato is an ordinary high school student, and Miku is an ordinary teacher except for her short height. They are childhood friends, and enjoy their life at the same school together with other classmates. But just before the summer holiday, Nagato is ordered to tidy up the school library with Miku. And that night, Gennosuke, Miku's grandfather, tells them that they are fiance and fiancee. They get totally confused to hear that. Their a little bit different summer holiday starts now....
Main characters realize mutual sympathy during library work, but then it's a normal school story without distinctive story and with side heroines occasional interaction. Just a heart-warming story, and only a single heroine route has some twist. Common route is quite long, but individual routes feel too short after it.
7. Katakoi no Tsuki 片恋いの月  Studio Ryokucha 1 You are playing as a student that has lost his mother while he was young, and your father is always away on business. You do have a liking towards forgotten Japanese culture and folklore. Luckily you have a classmate who shares the same hobby as you, and she helps you to form the Folklore Club at your school. Along with your childhood friend, student council member and underclassman; you begin to plan for the upcoming school festival, much to everyone else's chagrin.
It's a time loop story till school festival. Basically, common route is comedy with bakage elements, but individual routes touch heroines problems and thus bring seriousness to it. There are first lap routes, second lap routes and also a True route. It's a decent work overall.
8. Kimi ga Aruji de Shitsuji ga Ore de 君が主で執事が俺で  Minato Soft 12 Due to family troubles, Ren Uesugi and his sister, Mihato, leave their home. They end up moving to the city but find themselves with a lack of money.

There is an English review
9. Koufuku no Shokutaku ~Shiawase no Hane~ 幸福の食卓～しあわせのはね～  Honey Soft One day, when Hiroki was about to get on a bus, a girl asked directions to him. Due to this, he missed the bus. But he was surprised to hear later that the bus he had missed had a serious traffic accident.... Shortly afterward, his father gets re-married, and a new younger sister, Otoha, starts to live with him, whom he met at the bus stop the other day. One day, he wakes up late, and leaves his house without eating breakfast that Otoha cooked. Since that day, various ominous things happen around him....
Nakige with good atmosphere and taste. There are only three heroines, and volume is thin, but price is also only half the usual one. Graphics are mostly rough. Sentences are very simple, but feel sincere. If feels more like a doujin game.
10. Meikuru! Welcome to Happy Maid Life!! めいくるッ！ Welcome to Happy Maid Life!!  ASa Project The protagonist is an ordinary student, enjoying his school life with his friends and classmates. One day, his homeroom teacher tells them, "We are having a training student from Japan Maid Academy." Maid? Academy? They don't know what's going on. On the next day, the maid comes to his school, and they panicked. This is a slapstick school maid adventure game.
It's Giga partner brand. Not exactly a moege, just comedy main route + serious individual routes. But scenario is half-hearted, so it ends up neither scenario-oriented, nor moe-oriented, nor erotic-oriented. Individual routes are very short, under 2 hours time, so not too deep.
11. Scramble Heart  Bonbee! Hayato's parents went abroad on business one year ago, and he has been living with his sister, Yoko, since then. It didn't take long until they became close..., meaning they slept together. But one day, Natsuki, his classmate, tells him she loves him, and they start dating. Sex life at home and pure love life at school.... Which will he choose...?
Is there such genre as half-nukige? Because this game is exactly like that. Following Yoko intimate relations at home inevitably ends up a nukige, but if school girls are targeted instead, it becomes pure love genre instead. Can't block it because of that, but it does not worth any further discussion either.
12. Touka Gettan 桃華月憚  Root 1 Touka Gettan is set in the land of Kamitsumihara, where traces of magic and legend can still be seen. The land has been under the protection of the Kamiazuma clan since it was founded. The story revolves around Touka Kamiazuma, the main protagonist, who has lost all his memory, and his body has stopped growing. It sounds like he is in misery, but he somehow enjoys his life with his mother. One day, he joins a high school located nearby, believing it will bring back his memory....
Dating SIM with unique atmosphere and initially zero voicing (fixed only seven months later with new release). Will watch at least couple anime episodes to taste it.
13. Tsukutori つくとり  rúf 12 Kaoru meets Kudou on his way to work. Kudou is on her way to the scene of the murder to investigate. By following her request, Kaoru starts to investigate the murder case with her, and they find another dead body hanged from a tree soon after. According to people living nearby, a hanged dead body is found every year around the annual festival. They treat it with care as a sacrifice to Tsukutori, the local deity. Kaoru and Kudou don't believe it, but they face a series of mysterious accidents...
rúf managed to get author of Steel - Ajishio Rockets - for their last title. There are two impressions that tell basically the same - it's a good long mystery game with perspective shift midgame. Can't say I'm a big fan of ordinary life mystery to pick it up right now, but it's a good candidate for extra review of the year.
