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.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

超短流程前传故事,有许多细节呼应
Developed by VISUAL ARTS/Key and published by VISUAL ARTS, planetarian: Snow Globe is a standalone kinetic visual novel that expands the universe of the acclaimed planetarian series by exploring events that occurred before the original story. Rather than focusing on survival in a devastated world, this prequel presents a gentler narrative centered on everyday life, giving players the opportunity to experience the peaceful days that shaped the beloved robotic heroine, Yumemi Hoshino. As a kinetic novel, the experience is entirely story-driven, offering no branching paths or gameplay decisions, allowing the narrative to unfold exactly as intended through carefully paced scenes and emotional storytelling. The game revolves around Yumemi's work at a department store planetarium alongside her supervisor, Satomi Kurahashi, and other employees. Through ordinary interactions and workplace routines, the story gradually builds meaningful relationships that highlight Yumemi's innocent curiosity and unwavering dedication to bringing happiness to visitors. While the premise appears modest, the writing succeeds by transforming everyday conversations into heartfelt moments that emphasize friendship, compassion, and the quiet beauty of human connection. Fans of the original release will appreciate seeing familiar characters before tragedy struck, while newcomers can enjoy the story without needing extensive knowledge of the previous game. Visually, Snow Globe delivers a polished presentation that perfectly matches its calm and reflective tone. The detailed backgrounds capture the welcoming atmosphere of the planetarium and its surrounding environment, while expressive character artwork helps convey subtle emotions throughout the narrative. The snowy scenery and warm indoor settings create a pleasant contrast that reinforces the story's nostalgic mood. Every illustration feels thoughtfully composed, allowing the game's emotional moments to resonate naturally without relying on elaborate visual effects. The audio presentation is among the game's strongest features. Japanese voice performances bring warmth and personality to every conversation, making the cast feel genuine and memorable. The soundtrack complements the emotional pacing with gentle melodies that enhance both cheerful scenes and more reflective moments. Support for Dolby Atmos binaural audio further strengthens immersion for players using headphones, adding a greater sense of space and realism to environmental sounds and musical compositions. Combined with the ending theme, the sound design plays a major role in creating an unforgettable atmosphere. Since Snow Globe is designed as a kinetic novel, there are no puzzles, combat encounters, or alternate endings to discover. The experience is relatively brief, but its concise length ensures that every scene contributes to character development and emotional progression. Players seeking traditional gameplay mechanics may find the lack of interaction limiting, yet those who enjoy visual novels focused on storytelling will likely appreciate the uninterrupted narrative flow. The game also includes support for multiple interface languages, touch controls, and Steam Deck compatibility, making it accessible across a variety of platforms. What ultimately makes planetarian: Snow Globe memorable is its ability to find emotional significance in ordinary experiences. Instead of relying on dramatic conflicts or constant plot twists, it celebrates simple acts of kindness, shared conversations, and the bonds that form through everyday life. The prequel enriches the overall lore of the series while giving greater emotional context to Yumemi's character, making later events even more poignant for returning fans. Even as a standalone experience, it succeeds in delivering a touching and sincere story that lingers long after the final scene. Rating: 9/10

末日前真的好温馨。
前传,粉丝向,巨短
好短,,, 画得好可爱
这个也牛逼
星之梦的前传,剧情很短,BGM很有感觉,遗憾的是这样的日常很快就被战争毁灭了……
1.5小时的视觉小说
流程不长,甚至有些过于短了,当然是跟原作比起来,原价18有点贵了,建议打折的时候买,原作玩完后劲还没过的时候玩一下前传挺不错的
