A cozy horror game. The video game that most feels like performing an eldritch ritual. The writing is vague, deeply pretentious, and serenely beautiful. Not for everyone, but I have given this game my heart, hours of my life to its wiki, and it has rewarded me with dreams of a fanciful mythology. I don't usually remember my dreams, but I do remember Book of Hours.
TL;DR: This is a game you'll either love or hate, there's no in-between. If you like games that don't hold your hand and leave you stumbling in the dark figuring things out, this is for you. If you like learning on your own, taking notes, maybe making spreadsheets recording information you learn, this is for you. If you like reading a LOT of text and are willing to spend your time reading through every blurb looking for clues (and there are a lot of those), this is for you. This game is better experienced (in my opinion) when you take a slow, methodical approach, and don't use wikis or guides until you've played at least one full playthrough. It is hard, yes, but the satisfaction of resolving a mystery completely on your own can't be described with words. It took me 40hrs to reach the point where I could end the game, and 60hrs to actually get my first proper ending. I skimmed most of the text early on before realizing that it very much told me ways to make use of the skills I'd acquired and what could be made with them. I didn't realize until very late that I could re-read texts to generate memories, or use lessons in similar skills to progress a skill I was more interested in leveling. Conversely, I found out that some crafting recipes were exclusive to certain skills even if others had similar aspects, so I got to learn a lot about crafting. I also didn't know I could read texts without matching the aspect requirement, so the early game was a striggle. OTOH, I never had problems with curses or afflictions since I always had full mastery when reading. Had I not made those "mistakes", I probably would've been able to beat the game far, far earlier. However, that didn't detract from the experience regardless. All in all, I'd recommend this game to those who like reading and aren't looking to win, but rather experience the game in full.
I kinda fell in love with this game. It's a game about finding paths to do what you seek. There's probably 100 different ways to win (and I'm not talking about the 101 different endings). It does take a minute to understand what's going on, but once you do, then there's learning, and advancement, and deep learning and I really enjoy figuring out all the systems in the game. I read a review once that said this isn't a game you get all the achievements on. I think for most people that's probably true, for me... I have all the achievements and experienced all the endings. My biggest recommendation... you'll want to bring a spreadsheet to record info about your playthrough in. Oh yeah... one more thing... the DLC makes the game 100% better. Definitely pick it up even for your first playthrough. It adds a mechanic to recall visitors any time and that is really needed to make the game more fun.
I think this is the game I wanted to play compared to Cultist Simulator. It feels like the developers listened to what main hangups from that game and mixed it up to make something real special. Rich lore, beautiful art and giving the player the time they need to experiment and explore. There is a lot of similarities between the two, heck it is evidently the same universe given there is a lot of overlap with the books you have like the Rose of Hypathia and the same style and even some cards elements. If you know how those elements work in CS, it comes very handy here in Book of Hours. But I feel a lot more at ease to take my time and really invest in the world, explore and develop my skills compared to Cultist Simulator (CS). Book of Hours is much like Cultist Simulator in which you have a set amount of cards, time and things to manage periodically. But it also differs, CS is much more of a tabledeck which had its own problems, Book of Hours on the otherhand has a far bigger map layout to focus your attention and explore. It also gives the universe a sense of depth that was difficult to gauge previously. But that's understandable considering your focus in CS was something far more different. In Book of Hours it is mainly the library and man is it massive but it also feels like you have a lot more to do and at your own pace, compared to the punishing one of CS where you had so much things hampering you. I remember starting out Cultist Simulator I was more annoyed than I was interested and I was plenty interested in the game. The problem with Cultist Simulator is it is a game that has the universe itself conspire to put you in the dirt. Despair, police,money, health, you name it, if there is something it will kill you before you can even figure out what it is. It makes sense considering how the government understandably doesn't want people to start Cults. But it requires a lot of time to invest in, especially because early game is boring as hell and you can spend a lot of time in that section with not a lot of resources and too many things to balance. There is also no real saving so if you mess up or something unexpected happens, tough luck. New playthrough which will take hours upon hours to go through to even go back to that prior stage you were at and I'm not even exaggerating. I spent 10 hours on one run and I only just about got the groundwork for the cult established and I still had no clue what else I was missing or doing. And because the game is incredibly punishing it doesn't really let you develop and allow one to explore the mechanics and arguably the fun parts of the game which is much later in the game. The fun is retrospective and honestly even when I figured out the cult aspect it didn't even feel that rewarding. Like Learning how the cult actually works and inducting members was great but 30 hours into that game and I still never got into how the rituals and the lovecraftian elements because I was too dead to look at them or I haven't managed to get through the dreams or areas yet. Time is not on your side in that game and it makes every run incredibly precious because they can and will last hours and yet it is also incredibly tedious because you have to continuly keep track and balance time which can be painfully slow at times too. It is still addicting and compelling but the gamepplay itself is a massive drag and I am still confident in saying that. Book of Hours is not that. It is forgiving, the game even admits as much. It lets you expand and gives you the chance to develop and expand. It feels so rewarding to figure out how some of these lessons and skills work. I was worried because of my experience with CS that I couldn't develop any skills but I did and I don't think I could have. It took me a while and I'm still working out the kinks but man I'm already really having fun experimenting and broadening my skills. I feel more attuned to the aspects of this game because the system feels a lot more clearer, compared to Cultist Simulator where I felt like I was chucking anything and seeing what worked on top of the stress of my crimes being on display but no means to prevent it because I have a third despair card coming and little money for books to expand my knowledge. It makes sense too I guess, you are a librarian and this is your job and man is it a great one. I'm actually having a lot of fun with this one and I have a good feeling it will continue to go that way. There's still tons more to explore and do and I'm actually looking forward to it. You actually get to look at the books, see what works with the other devices throughout the library house and so much more.
Confusion is a question, and the gamer's answer is always Yes. What if I told you this game left you washed up on a beach with no instructions, forced you to read hundreds of pages of text just to try to puzzle out what is going on, and made Monopoly look fast paced by comparison? AND YET. It worms its way into your brain, my friends. There is so much lore here that re-reading books in order to jog your memory is an integral part of the game. It's so meta that I don't even know if that last sentence was literal or metaphorical. And somehow the more time I spend here the more time I want to spend. I played this game for a normal-game amount of time - say, 50ish hours - before throwing up my hands and saying "nothing makes sense, I'm out." Picked it up again a year later and the clues were seemingly everywhere. Clearly the game hadn't left my head, but had been percolating in my dreams. Took me another hundred hours to finish my first runthrough. I'm 250 hours in now and barely started on my third runthrough, with over 70% of the achievements - all hidden, of course - left to find. I'm not going to complete them all. But just contemplating what the heck they could possibly be... This is not a fast game. In fact, for a game in which the primary mechanic is time passing, it it strikingly blasé about the actual passage of time. There are very few (and clearly marked) ways in which you can fail this game, but you can do nothing until the cows come home. You can feel like you're making no progress for a very, very long time - to the extent that just putting a bust of Random Person in its correct little niche feels like a cause for celebration. If you're a person who likes to read, if you're a person who at least doesn't mind that feeling of "there's something more here I'm not getting yet" tickling at your brain, if you want to immerse yourself in a world that is very clearly Not Quite The Same as our own, this game is for you. If you're a person who gets frustrated (I won't say "easily" but rather "at all"), if you're not looking for a WAY longer commitment than most games, if you will check the internet for a solution: I'd give it a miss.
