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 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.

此為正篇的前傳,主要交代女主角(機器人)的在人類還繁榮的時代的日常生活。 故事的結尾解釋了為何夢見會留下人性化特色的原因 有玩過正篇的人務必遊玩本作,遊戲時間不長。
非常简短的故事 来自梦美的、数十年前的那琐碎的日子 很遗憾没能再听一次Gentle Jena
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……
