Prices
The United States storefront in every case, so this compares stores and not countries.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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): 56.83/day in the week to Jul 17 → 3.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

This is easily one of the best games I have ever played, and I have played WAY too many games. It appeals to my sensibilities in a way few games do, and trusts the player to get in time with its rhythms, and immerse themselves in its strange, compelling world. The gameplay loop is extremely satisfying, you feel like you are constantly making progress and hitting milestones. Looks cool, the musics nice, beautiful written. Totally unique in its tone. Truly simulates the experience of being a librarian who is going slightly mad as they restore this old house and grapple with the mysterious knowledge contained within. I've just the hit the point where I've had to create a spreadsheet to help me and I have never been more locked in.

Absolutely loved this game. First time playing something where figuring out how to play is part of the game, and I found I really enjoyed it. I tried to purely memorize at first but ended up keeping a journal to keep track of everything I needed.
This is way more chill than Cultist Sim, I will constantly restart a new save to go through it again. I will play it while reading or watching other stuff, or ill just adjust the libary.
This and it's predecessor (cultist simulator) are games unlike any others. Even trying to describe the genre is awkward, calling it a crafting game seems reductive but it's the best fit. They're great for a particular type of person and not really for everyone else. It's confusing at first, then still a bit confusing for a while afterwards. There's no tutorial or tool tips, you're expected to learn everything yourself through trial and error, though punishments are light and reversible. The small intro teaches you the most basic actions but you'll likely be unaware of what you're actually doing at that moment. Once you get over the initial steep learning curve and played around a bit the basic game loop will reveal itself. Learning how to play is part of the game and part of the fun and figuring stuff out is very satisfying. The writing is amazing. If you've played sunless sea/skies you'll instantly feel at home. It's very Lovecraftian in feel. The visuals are nice and fit the vibe and the attention to detail is great. If you love reading, figuring stuff out yourself with no handholding and are happy with an experience where puzzling out the mechanics is actually part of the game, then you'll likely find a lot to love here. It's slow and require patience and perseverance, but stick with it and it's a super cool game.
本体通关,dlc还没玩:系统比前作简化了很多,是好事也是坏事:上手要更快,惩罚几乎为0,对于新手来说还是很合适的;但与此同时深度可以用粗糙来形容,整个玩法循环随机性也几乎降低到0,很难想象重复游玩的乐趣。 不得不说,作为一个小制作组,凭借独一份体验收入提升的同时,对于已有的几部作品上心程度反而是下滑:从《密教模拟器》的dlc到《司辰之书》能感觉到用心程度越来越低,制作上越来越粗糙,在前作虎头蛇尾这种级别的制作下继续拓展新的作品也没法说是一个很好的选择。 续作crpg可能还会买,没办法,就吃神神叨叨的文本这一套。希望制作组能够认真对待已有作品吧。
Как и симулятор культиста - великолепная игра в своём жанре. Но также как и в симуляторе культиста - ОЧЕНЬ много гринда. Я не согласен с утверждением в главном меню, что "это милосердная игра". Она жестоко не объясняет тебе, как тебе играть, что тебе нужно сделать и какими способами этого достичь. Считаю совершенно не зазорно использовать вики и гайды во время прохождения, в виду обилия "энциклопедических" внутриигровых знаний. Но будте осторожны, даже после прочтения гайдов есть вероятность, что вы не поймёте, что надо делать.
I realized I haven't reviewed this yet - it's incredible. One of my favorite games of the last five years. The worldbuilding, tone, and the way the gameplay really asks and rewards your engagement is like very little else out there. I've never played a Weather Factory game before, but the very next thing I'll be doing once I get out of playing this game nearly every day is getting Cultist Simulator and checking that out. Incredible work.
