Prices
The United States storefront in every case, so this compares stores and not countries.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Sep 1 → 0.71/day in the week after.
Reviews, worldwide (the counter carries no country): 1/day in the week to Jul 21 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

欢迎光临星象馆 这里有无论如何都不会消失 美丽的无穷光辉,满天繁星在等待您的到来 剧情一般算是补充了一点背景,但是高清的梦美更可爱了。
梦美还是那么可爱,音乐也不错,剧情要我深度思考是办不到的。

This is only worth reading if you read the OG Planetarian and wanted to get a little bit more about Yumemi's life before all the bad stuff starts to happen in the game's world. It'd be like the equivalent of having a two hour look at life in Rapture before the main BioShock events occur. As a story, it's kind of bland, but I'd recommend it just because I appreciated the OG a lot.
"Planetarian: Snow Globe" is a short but beautiful prequel to "Planetarian: The Reverie of a Little Planet". While it doesn't have the same emotional impact as the original, I really enjoyed getting to see Yumemi before the events of the first Visual Novel, as well as the people she worked with and the simple moments they shared. It adds more meaning to Yumemi's character without feeling unnecessary. I also recommend watching the movie [b] "PLANETARIAN: HOSHI NO HITO" [/b] after playing both Visual Novels. Seeing the peaceful world presented in this VN and then returning to the ruined world of "Planetarian: The Reverie of a Little Planet" makes the story feel even more bittersweet. The movie brings everything together and gives the entire story a much greater sense of closure. It's another small, beautiful story from Visual Arts/Key. If you enjoyed the first one, "Planetarian: Snow Globe" is definitely worth experiencing. Here's my "Planetarian: The Reverie of a Little Planet" old review, just in case u want to read it: [u] https://steamcommunity.com/id/BlessedMontana/recommended/316720/ [/u]

不到一小时的前传,很可爱,手柄也完全可以操作。
Planetarian Snow Globe é o exemplo perfeito daquele tipo de jogo sobre o qual tu dizes “meh, não foi mau nem foi bom”. Realmente não tem nada no qual se destaque, mas tampouco é uma experiência ruim. Como prequela, até que tá ok, é interessante a pequena adição que faz ao lore da VN original e suas conquistas como Visual Novel chegam até apenas isso. Não vou reclamar de nada porque o preço foi justo, comprei em promoção por menos de um dólar então nem nisso posso criticar. Em conclusão, meh. Que pena que não exista uma opção de análise mista,
星之梦的前传 那句亘古不变的台词一出来很难不被硬控 补全了以前的星象馆和一个约定 建议先玩本传再玩这个会更感动,也更遗憾...
