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.

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.

This isn't a game, this is a visual novel. There are no gameplay elements whatsoever. It is not like a "choose-your-own-adventure" novel, there are no choices to choose from.

Planetarian uses graphics, music, and sound effects to tell a story. It's an excellent story, and I strongly recommend it.

Knowing that this Visual Novel was made by VisualArt's/Key, why are you reading reviews instead of Insta-buying it?

Seriously though[/b]

Planetarian ~the reverie of a little planet~

Plot/Story 9.8/10
Animation/Design 9/10
Audio/Soundtrack /10

Plot/Story 9.8/10
Set in a post-apocalyptic world where humanity is on the verge of extinction after the failure of the Space Colonization Program and Nuclear warfare, "Junkers" scavenge anything that could help them to survive. Our nameless protagonist discovers a Pre-war Planetarium and enters in search of useful supplies, he is then greeted by Hoshino Yumemi who offers to show him a special commemorative projection especially reserved for the 2,500,000th customer(although he is in fact the 2,497,290th customer). Despite his aggravation with her, he agrees to attend her show. However, the projector device, "Miss Jena", has broken down and is in need of repair.

I'm lost for words for this one, the story is simply magnificent. The story is relatively short, you can finish the entire Visual Novel in a little over 3 hours depending on how fast you are at reading. But despite being short it's definitly memorable, I haven't felt this moved since Narcissu[/u], the story was definitly a sorrowful one. You are guranteed for feels in this one, even if you're the type to not cry at things like this (like me) the story is still very touching, I can't wrap my head around the fact Yumemi stayed at the Planetarium for 30 years straight in a complete solitary state and yet still be the talkative goodhearted person she is, I understand it's because she's a robot but damn.

Animation/Design 9/10
Doesn't really differ from most Visual Novels

Audio/Soundtrack 10/10
The soundtrack is astounding, it's just magnificent and beautiful. Every single track falls into the right situation and emotion. The 'Gentle Jena' track is a great example, it went really well with the scene where the protagonist watched as the Planetarium did it's thing, as the track played there was a sense of triumph about how the repairs paid off and the feeling of amazement and wonder as the protagonist looks up at the stars which is supposed to be a rare sight in his time.

Review Conclusion
I loved Planetarian ~The reverie of a little planet~, it's a beautiful short story that is guranteed to leave you with feels, that story will stay at the back of your mind, the time the protagonist spent with Yumemi, how she was abandoned and how she's slowly breaking down.. it's such a sad, memorable story. Planetarian ~The reverie of a little planet~ was developed by VisualArt's/Key, widely known in the Visual Novel community for creating CLANNAD(Which is due for it's release on Steam around Jan 10!), Air, Kanon and more. Planetarian ~The reverie of a little planet~ is really worth the money I gurantee it.

A stunningly beautiful tale of a broken world full of broken people and broken machines. Each minute spent with Yumemi is one to treasure and hold close to your heart as her childlike innocence is the only beacon of hope left in a dead city. Filled with a soundtrack that fits the mood perfectly, Planetarian presents itself incredibly well. Hats off to KEY for being able to make the audience grow so attached to a robot in such a short time. Absolutely worth the time and money.

Key Visual Art's is the Best story-telling game developer out in the gaming business, have finally hit Steam! (Took them long enough!)

Heads up though this is not what you would call a game, it's more like an automatic book aka Kinetic Novel, which mean no interaction just reading and listening.

For me Key (Key Visual Art's for short) have been my favorite company ever since i first watched the anime called "Clannad". After finishing both seasons, i needed to fill the emptiness in my heart with more anime which were almost as good or closely like "Clannad", those were "Air", "Kanon", "Angel Beats" and "Little Busters!" (though LB! was 3-4 years later). What do they all have in common? Made by same company and highly rated anime and highly recommended. So Planetarian should'nt be an exception! Although all you do is read and listening. You will be dragged into that world, feel every happiness, sorrow and pain and ofcourse you will get attached to one of the characters! (in this case just one). Let us not forget the Background music! THOSE are the what i call Re-FEELer (see the pun there?) Every time i listen to one of Key's produced music, i end up remembering those moments in the anime/game and just standing there crying... Happened to me once at school when i was careless and the Yumegatari (a song from the anime "Air") was played my mobile, I sat there in class and dropped tears... just... just beautiful songs a-and.... it's so sad... but still so good...

My conclusion would be:
Buy it if you rather want a good story to FEEL more than a gameplay. Cause if you want both get "To the moon" but if you want a gameplay? Well... wrong place!

Never in my life had I tried a visual novel, heck I didn't even know such a thing existed, being the adventurist guy that I am I said "eh why not give it a shot??, YOLO!!". Well one thing is for sure, that ending will definately put your manliness to the test. Great story. you can click away at your pace or just leave it in auto mode kick back and relax.

WARNING: severe feels overdose may cause heart failures, hipertonia or uncontrollable indiscriminate cuddling.

This story combines "There will come gentle rains" by Ray Bradbury, Terminator by James Cameron (dreams of Kyle Reese) and C3PO. Heroine would never shut up unless someone could die because of her endless chatter.

And answering people who still don't know if it's worth its money: it consists of concentrated win and nothing else. You can buy Clannad which has more win thinly distributed between gigabytes of text, endless bad ends and hours and hours of reading. Or you could buy this one, that has less content, but incomparably bigger win to vontent ratio, and cry from the beginning till the end credits, like I did. I didn't even know that I could cry for 4 hours straight.

Absolutely beautiful. This kenetic novel, made by the inspiriational people Key (if your familiar with Kanon or Clannad). The story of Planetarian the Reverie of a little planet is well and truely unlike any other story you will hear and one that should not be missed. A strong and moving story that will change your views on the world around you. Unmissable if your passionate about stories and emotions. I strongly recommend playing it start to finish in one sitting, especially if you want to take it in to a full measure, providing you can keep at it for 2-4 hours.
Simply my favorite story, visual novel and Key title to date.
