And as he enters he is greeted by Hoshino Yumemi, a companion robot.
Without a single shred of doubt, she assumes he is the first customer she's had in 30 years.

It's a nice & sweet short story I've read. Planetarian ~the reverie of a little planet~ is made by the legendary company "Key", well known for creating Angel Beats!, Clannad and Little Busters! anime series. This game will guaranteed to touch you with the feels and make you cry.

Good points
- Fantastic character development & interactions between the two unique characters - The junker guy & Yumemi the gentle robot.
- Very well presented that will easily set your mind into the wonderful world of Planetarian.
- Delightful soundtrack & story. I love the soundtrack especially Gentle Jena, one of my favorite songs. The melody is so touching and charming. Listen to this piece & you'll be blown away https://www.youtube.com/watch?v=lR4dw_B423E
- Beautiful illustrations. Yumemi looks pretty adorable & I like how it's suits her personally well.

planetarian may be a short story, but it is one that sticks with you in the back of your mind for a very long time. I still remember when I first finished planetarian years ago. It is as soul-crushing as it is beautiful, and the impact still holds up against the best of Key's catalogue critically acclaimed visual novels. Thematically, it shares many ties to Key's most recent game Rewrite, which could be interpreted as an attempt at expanding upon the themes introduced in this game in a grander narrative. With that in mind, I would definitely recommend the two as complimentary to each other. If you're perhaps new to visual novels in general, then planetarian is definitely a good place to start. It demonstrates some of the very best of what visual novels have to offer in a tiny package; a small taste of what you can look forward to in the world of visual novels. It's also serves as a great appetiser to Key's brand, something to prepare your palate for the main course of Key's much larger games. I'd recommend this game to anybody who appreciates a good story that touches on some really powerful themes. It's not for the faint of heart, but once you've managed to overcome the pain it's bound to put you through, you might come out with something you didn't have before.

A beautifully woven work of textual art would be selling short the impact this tale would have on you. Stop reading this, cancel your appointments for the next 4 hours and play it now.

If you've played it before, this is a polished version of the highly acclaimed original that never made it to English speaking shores. It's worth every penny and then some. I couldn't be happier with it. Play it again.

Deep inside the old sarcophagus city, while searching for food, weapons, or resellable scraps, you make an unlikely discovery: What you'd assumed to be an abandoned military facility is actually a pre-war planetarium. And as it turns out, the custodian robot is still welcoming customers after all these years.

Let's talk about planetarian ~the reverie of a little planet~.

It's a kinetic novel (a visual novel without any choices or other interactive game elements), so the only thing that the player/reader controls is the pace of the story. Do what you will with that information.

Originally developed by Key in 2004 and recently published on Steam by Sekai Project, this is widely considered a classic in the VN community, and a very worthwhile addition to the still meager selection of good visual novels on Steam. It's a short story about a world full of desolation, hopelessness, cynicism and resignation, and about a little robot girl who's immune to all of it. It's also about going stargazing in a world without stars.

The backgrounds and character sprites in planetarian are somewhat sparse in direct comparison to some of the more visually bombastic VNs out there. It is however very evocative, and with that it falls in line with the writing. The whole novel follows a slow pace -- never dragged out, but certainly deliberate. It leaves plenty of time for you and your own thoughts, and I urge you to take advantage of this invitation. I ended up with just over three hours of total playtime, which included some breathing room for the fantastic voice acting.

Any good visual novel swings in tune with its soundtrack, and planetarian is no exception. Opening with the music box lullaby "The World of the Stars" it immediately offers you a glimpse of its gentle mood. Tracks like "Song of Starflight" accentuate the day-to-day interactions of the main characters with a lax and childish air, while the perhaps most iconic song of the roster, "Gentle Jena", cushions some of the more tender scenes in an aura of warmth and belonging (and I would encourage you to keep that last one playing in the background while you read the rest of this review).

Visual novels as a medium don't lend themselves especially well to twitchy action stories, and despite the occasional surprise in that regard, the bulk of planetarian is about its characters and their interactions. Of the two main characters, only one actually appears on screen, and it would be a fair assessment to say that the story is about her, in several ways.

Yumemi (translated as "Reverie" in some localizations) is not the kind of quasi-human A.I. that we're used to from the likes of Cortana or EDI. She is a robot programmed for a very straightforward purpose. She oscillates between toddler-like naiveté at best, and robotic-algorithmic behavior at worst. So why do you entertain her thoughts of repairing the old projector? Why do you, a looter perpetually on the verge of starvation, end up tacking another night onto your stay at the old planetarium?

This story isn't about what Yumemi is, but about what she represents.

Spending valuable time and energy on a planetarium of all things should feel frivolous, yes, downright sacrilegious. But there is something peculiar inside you, easy to explain away as idle curiosity about the starry night sky that you only know from old people's stories. Something you probably didn't think you still had. They say there was a time before the war, before the planet was shrouded by a thick layer of acid clouds, when people were able to look at the stars whenever they wanted. When there was still a notion of mankind eventually travelling to, and settling on, foreign worlds.

Back when people still had hope for the future.

Yumemi was left behind at the beginning of the war, and despite not having had any sort of human contact in years, she diligently awaits the day's customers. There's only one thing she wants out of this existence, one thing she wants to do more than anything else in the world: to show you the stars.

The little robot girl, once built for the simple goal of caring for the planetarium's customers, ends up fulfilling a much grander purpose. Tucked away in her own little corner of a gray world inhabited by people who have forgotten what it means to be human, Yumemi is a shining beacon, a time capsule, a reminder that there is a star-filled sky right behind the acid clouds. Yumemi is the child, the lamb. She embodies innocence, childlike wonder, relentless optimism. Looking into her eyes, you cannot help but feel deeply ashamed for what the world has become.

What was it, then, that made you stay at the planetarium? Was it really just idle curiosity? Or is there more to this little thought in the back of your head after all? Do you feel in your stomach what the place emanates? Does Yumemi give you the strength to dare to form the words, that maybe, just maybe... there is some hope left in this world? That there is such a thing as "the future"?

You should read planetarian if you have any interest in visual novels, if you haven't experienced a good story in a while, if you like looking up at the stars and wondering what the future holds, or if that little spark deep inside you that is almost drowned by cynicism needs a little bit of nourishment. Wholeheartedly recommended.

Planetarium is a kinetic novel developed by Key (best known for Kanon, Air, Clannad & Angel Beats). What first served as a game tester for Kinetic format turns out to be a hit sales when it was released back in 2004.

I have played this novel over again and again on multiple platform yet the warm feeling of this novel still stucks in the back of my head like I just played it yesterday. The feeling that you get from this novel is overwhelming and the soundtrack delivers an epic blow alongside with the story. The graphic, while it is from 2004 is quite good and the design is also detailed.

Planetarian is a VN that I would always recommend to my friend who wants to try the VN medium as this VN is delivers such a great impact despite its short story.

Also, you should try listening to the Drama CD after finishing the game. It provides a proper conclusion to the story of Junker and additional side story regarding the Great Nuclear War.

I have already played this game before it was licensed and I even bought it when I found an iPhone version. The fact I'm playing it for a second time means that it's doing something right.

Developed by Key, 'Planetarian: ~The Reverie of a Little Planet~' takes place in a post-apocalyptic Japan. The Junker (the character you follow) hears rumours of a city that hasn't been exploited by other scavengers. In hopes to claim any goods, the Junker stumbles upon nothing but ruins and a robot girl named Yumemi Hoshino.

The story itself isn't very long, which is good considering it doesn't have a thousand story arcs like Clannad or Rewrite (some of Key's other works). It's just the right length to develop your characters and see them interact with each other as they try to overcome the problem at hand.

The Junker starts off as a jerk (although that's understandable) and he I didn't find him ver likeable in the beginning. What I don't like the most is that we are given bits of his past but they act more like references than tools to develop his character.

Yumemi, however, is the true star. She's a very thoughful and respective robot that takes care of the planetarian in the absence of civilization. Her attitude and general presence is almost heartlifting, and if you engrose yourself in the game you might even grow a smile on your face. You almost forget she's a robot by the end of the game.

The music is pretty nice. It's calming when it needs to be, but there are moments when the music stops and the only audio playing is the rain, which is really calming.

Speaking of which, the atmosphere is mostly pretty cheerful. Most of the time it's just the Junker and Yumemi talking, and the music in the background works very well in this respect. There are times when the rain just goes and it lets you take in everything you are experiencing. You can also tell by the end of the story just how heavy things are getting.

If you are considering this game I highly recommend you buy it. If you aren't interested in a story with no gameplay stay clear of this one there is no gameplay other than clicking to prceed to the next text. There aren't English voice actors either, so if you aren't fond of listening to two Japanese actors talking to each other I also recommend you stay clear of this game.

So, this is another key's sadness visual novel, I have played Clannad and watched Clannad, Air, Kanon, and many key's animes. This time key brings us a sadness but thoughtful story with a robot girl whose name is Hoshino Yomemi, which means the beautiful dream of the stars. I have read the whole Planetarian novels after played this game, so that I know the whole world of this novel series.Yomemi is a lovely girl, I DON'T think she is a ROBOT, but a HUMAN with all the beauties and she stands for the brightness of humanity. She is innocent and just like a child. Human destoried everything but she still believed that everything will become fine one day. I think the precious memories of Yomemi are the most moved part of this novel and I cried for nearly 2 hours after I watched that part. After played this game, I thought a long time, why human beings began to kill each other? Maybe they lost their emotions like love and mercy. After all, all these loves and mercies are given to Yomemi and she became the hope of human maybe. Though her body dead in the end, but her spirit was taken by us. By the way, the next novel called Man of Stars(maybe, I read this story in Chinese), in that story, our main character became a old man and show other people the beauty of stars, just like what Yomemi was done to him, and finally in a small village in South America, he dead with another robot which the same type of Yomemi, in that time, the South America was covered with ice and people could hardly survive. In that village, our main character teached 3 children many things of stars, knowledges, and some past stories. It's a sad end. Human couldn't avoid disappearing from this planet, but our spirit, our love, the dream of heaven, the heaven that won't be seperated, the hope, won't disappear.Actually, I think this game worth this price, in my opinion, it's even more worth than 60$, it makes us to thought what's the true love, what's the humanity, and I think it's even more thoughtful than some text book.

Behold, the first Key/VisualArt's visual novel to make it onto Steam! Sekai Project already announced that they will be releasing Clannad on Steam as well, so you can be sure that this won't be the last.

Note that Planetarian is a kinetic novel. This means that the player doesn't make any choices which impact the story, making it more akin to a graphic novel than a game. While many might argue that this would make it inferior to other VNs, the story is well written and satisfying enough where I am not bothered by the lack of choice. Both the artwork and the text are beautiful and bring the story to life.

So even if you don't normally play kinetic novels, I highly recommend you buy it anyways and try it for yourself. There's a reason Key/VisualArt's is as well known for their VNs as they are (hint: it's because they're geniuses). By buying this game, you are supporting Key/VisualArt's, Sekai Project, and Steam, which in turn will lead to more VNs being released on Steam! It's a quadruple win!

And thank you Sekai Project for collaborating with Key/VisualArt's to make this happen. Can't wait for Clannad!

Speaking of Clannad, make sure all you Clannad fans join our Steam group (we're very active!): http://steamcommunity.com/groups/CLANNAD

Ah. A work by Key.
For the unaware (especially those who enjoy anime),
Key is responsible for Visual Novels like Air, Clannad, Kanon, Little Busters, Rewrite and Angel Beats.
Most of those already have anime adaptations.
(Except for Rewrite, Kud Wafter and Planetarian)

While Planetarian might be too short to get turned into the usual 12-13 episode anime series,
if it gets the anime movie treatment,
I'd say it'll be a treat you should not miss.
Some comedy along with feels (the combo traits that have come to be associated with Key works)

PS: The first time I cleared this Kinetic Novel (outside Steam) had me shedding a few tears.

*If asked to which Key series this reminds me of, I'd say Clannad.
In Clannad we have a robot and a girl.
In Planetarian we have a robot and a guy. :p

picture an ocean. that ocean represents your tears. I am not exaggerating. enjoy your tears in this classic Key Visual Arts novel. the first time I read it was years and years ago, and I was probably in tears for almost an hour. this time around, re-reading it, even though I knew everything, I was left in tears for twenty minutes.

Simply beautiful

Amazing short story which, despite it's length, delivers superb character development. The music is very good and fitting as expected of KEY. And voice acting is just excellent. As of today, Planetarian is no doubt the best Visual Novel on steam - If you're into VNs it would be a sin not to buy this!

PS: Don't forget to check out Drama CDs with "after story"

A masterfully written story full of sad moments, uplifting moments and some downright depressing ones too. While it can be read from start to finish in 2 hours, it is well worth the price and then some. Even though it is just back and forth dialogue between a robot programmed to take care of guests at a planetarium and one man in a post-apocalyptic setting, you'd have a difficult time finding other visual novels that offer a more engrossing story. Key are kings of the genre and hopefully more of their titles will end up getting localised on Steam. What a great VN.
