planetarian ~the reverie of a little planet~ is a kinetic visual novel (meaning that there are no player choices to make) that takes place in a future dystopia where humanity is almost extinct so there are very few survivors. "Junkers" are one of those few and basically, they take items and goods from cities that have long been abandoned. One such Junker finds his way inside a "sarcophagus city," which is basically a city that has long since been uninhabited. In his attempt to find more supplies, he finds his way into a planetarium, one that had been spared from the destruction that the War and afterwards, the Rain had caused upon the rest of the city as well as everywhere else on the planet. (I'd explain what the War and the Rain are but that's better left for when you play the game itself.) Inside that planetarium, there is a companion robot who continues to work there, unaware of what has happened to humanity and the planet since the people have long since abandoned the city. I won't spoil more on what happens after the Junker's initial encounter with the robot Hoshino Yumemi but I will say that this story is at least partially about the relationship that the Junker (unnamed throughout the story) and Yumemi form.

Since I'll hold off on giving more spoilers, I'll go ahead with my review. I really enjoyed planetarian a lot. It has a very emotional story and the writing was excellent. There were very few proofreading errors but I liked reading the text along with listening to the voice acting, which was great. The voices conveyed the emotion of the characters, who were mainly the Junker and Yumemi. The art was beautiful, in the usual manga style, and I liked the visual effects, especially the ones of the falling rain. The various music tracks were beautiful, too, and all of the elements (writing, music, art, etc.) just fit so well together to tell a beautiful, sad story. I did end up crying at the end although I can't reveal why since that would be a major spoiler. Although planetarian was short, it definitely touched my heart.

Overall, I'd recommend giving planetarian a try. If you want a story to immerse yourself in, to enjoy as you sit back and watch, then this is for you. Although I did find it sad, I'd say that it was more emotional overall, as it stirred other feelings in me, too. I could go on some more about other things that I liked, such as the eventual planetarium presentation, but I think it's better for you to buy it and give it a go. ^^

This is not a game.

Firstly, I watched the anime before playing this game, despite I purchased it before the anime was released.

This is a visual novel that is filled with emotion and I must say that key did a good job in this game.

I enjoyed the anime and this is the same but the feels could not be stopped even when I have watched the anime. I find that the tears was flowing like a lake when I was reading this VN and I enjoyed it deeply that I read every word that was in the text. Some of the words are bugged, unreadable but overall I must say this is a great experience to people who enjoy VN.

To anyone that really enjoy reading, this is suitable for you are be prepare to have a packet or even a roll of tissue as tears are really leaking right now even when i'm writting this review.

I would totally recommend this game to everyone that enjoys VN and reading. GL as now my shirt is totally wet with tears.

This absolutely crushed me. Much like with Clannad, planetarian has left a mark on my soul that will remain forever. What a masterful balance between hope and despair, eclipsed perhaps only by Clannad, which ultimately blesses the audience with what they yearn for. A masterpiece nonetheless.

Every visual novel is like a book, either it's a good read or it's a boring read. This visual novel starts slow but becomes an extordinarly good read.

Planetarian revolves around the three themes of war, trust, and innocence from start to finish. It starts off feeling kind of hokey, but the story is self aware of that because the main protagonist intialy feels much the same way about the situation he finds himself in.

In summary the main protagonist stumbles upon an abandoned planetarium in a war torn ruin. What he finds there is a robot girl, a greeter for the planetarium, who appears to be blissfuly unaware that it has been thirty years since the world was destroyed in nuclear war. Her ignorance is exasperating yet her earnestness is oddly endearing and the main protagonist finds himself slowly warming up to her. And chances are you will too.

This visual novel can be a slow read at times, the spacing between letters is atrocious, and the whole story is dripping with setimentality. And yet if you can get past that you will find that this is a read that will draw you in with some of the best writing I have ever seen in a short story. The entire read will only take you about 2-3 hours, so I recommend reading it on a free afternoon or a chapter every now and again when you need a break from a hard day.

This is a good novel game for those who never play novel game because this game takes about 3~5 hours to finish. If you enjoy BGM, story, Japanese actors voice I believe you will enjoy this. I personally prefer to play in Japaese because I feel Japanese language makes me feel more touches (most likely it is personal preference). This game is very touch! Hope you guys enjoy. (The BGM 'Gentle Jena' is the best in the game and I purchased the soundtrack because of this BGM!)

This is a visual novel by the japanese studio Key, which is famous for their heartbreaking visual novels.
It does not offer any choices, it's short (it took me about 4 hours to finish it), and it's good.

Soundtrack contains 8 small masterpieces. Voice acting is even better.

My only regret is that there is no HD version.

Absolutely recommended for anyone, who is in love with the stars and visual novels.
That story will stick with you for a long time.

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
- Beautiful illustrations. Yumemi looks pretty adorable & I like how it's suits her personally well.

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.... do you want to feel the feels? Come with me and i'll show you.

Planetarium isnt just something to make you cry, or try so hard for you to feel something. If you know the works from Key you know more or less how the things go, the story it's short, it's a kinect novel, doesnt have choices or routes, it's a heart warming story, and a lesson about humanity and what makes us human, probably you will finish this novel with something more for your life. Give it a try, even if you are not in to VN, you'll probably like it.
