It's a complex and well-made game. Merely calling it a visual novel doesn't do justice to AI: TSF. It took me over two years to complete as I got distracted by other games. Still, I always had this game in the back of my mind nagging me to put it up again and tie up all the loose ends. Finally after revealing all the plot twists I can pride myself to be one of Tokyo Metro Police's cold case specialists.

It would take a hundred M. Night Shyamalans to come up with a story like this. I was on the edge of my seat from the first minute to the last, and my jaw dropped several times. This game is a miracle. Even with probably over a thousand crime books, movies and games under my belt, I was still blown away by the twists and turns and the clever writing, presented in a flow chart, leading through multiple endings via deja vu (or not?). They say the best stories are born out of real life, but this story is not (yet) possible, it has some subtle sci-fi elements, completely made up by the writers, which makes it even more captivating. I have skipped the lore element in many games lately after realising how badly they are written, in Somnium Files I didn't skip a single dialogue or commentary, and I clicked on every interactive item every time. The humor is absolutely my taste, I laughed out loud several times during my playtime. Besides the story, the presentation is also remarkable. The manga characters are masterfully animated and the soundtrack takes the experience up a notch. This is one of the few Japanese games where I recommend the English voiceovers, all the actors did a fantastic job. The user interface and design is clean and works very well. It's almost an insult to label this game a visual novel. All the gameplay elements are fun and engaging. This is certainly a fleshed out game that imposes a lot of ideas that are translated in a visually stunning way. This is a massive recommendation for anyone looking for a good crime thriller with strong emotions. You'll laugh, you'll cry, you'll be angry, you'll be sad, you'll be relieved, you'll be shocked, all mixed together in a carefully crafted way. I guarantee the characters will be etched in your mind forever and stay with you for the rest of your life. Upset! Regret! A-set!

The duty of a detective is tough, from time to time you'll find situations where witnesses or suspects are not willing to cooperate... Unluckily for them, their subconscious can't lie, and you my friend... Have the ability to interact with other people's subconscious Plot: The city never was a peaceful paradise, the scum is always there to destroy the day of whoever they feel like bothering that day, thieves, murderers, the yakuza... between other stuff. But on top of all the scum that lies on the world, there is one that has been terrorizing the city for years... The Cyclops Killer... A serial killer that kills their victims in very different creative ways, and signs his macabre act with a very peculiar act... He removes the left eye of their victims... You are Kaname Date, special agent from the Advanced Brain Investigation Squad, or "ABIS" for short. You've been after the killer for a long time, never been able to get a clear clue that places you behind his track, but today... it might finally be the day... In company of your trustful companion and AI computer, Aiba, you'll put an end to the horrible doings of the cyclops killer... Gameplay: The gameplay of AI: The Somnium Files is what you would expect from a visual novel, is a point and click mechanic that allows you to inspect different objects and talk to every person that you want. If you click on a person, you might get the opportunity to ask different things, and in that case a chart of options will appear with the different topics where the conversation can go. But that's not all... This visual novel has a bunch of quicktime events that you'll have to resolve when action comes into play... There are interrogation to suspects and witnesses that you'll have to take care of in order to get the answers that you are looking for... And finally... you'll have to think fast and now how to manage your time, allow me to explain myself... Mechanics: - Somniuns: As a special agent from ABIS you have one special permission, whenever the witnesses or the suspects don't want and/or are unable to cooperate with you, you can use the psync machine, a device that allows your consciousness to travel to the consciousness of the host. In there you'll be able to see a and interact with a manifestation of the host subconscious recreation of certain events. But reaching this subconscious truth is not an easy task, the path to it is blocked by barriers that we call "Mental Locks" and can only be triggered doing some kind of specific action. On top of that, you can only be inside of the host's subconscious for 6 minutes, if you stay any longer... you consciousness will be assimilated and absorbed by the host's subconscious and the traveler will disappear... - AI-Ball: Your left eye has been replaced for an artificial eye with an incorporated AI, we call her Aiba and she'll be your best companion during your investigation. With Aiba you don't even need a phone, she is everything you need, and on top of that, she is able to show you stuff that you would not usually be able to see, like X-ray vision, or heat vision, and he can even function when you are unable to act. - Flowchart: The story of AI: The somniun files it's a big one, and depending of your decisions inside the somniuns you'll affect the host in one way or another one, leading you to different information and different endings. There is a lot of key information that you need to progress through some routes, and if you don't have the route will get locked at a certain point and you'll need to backtrack and try a different route. That is a little bit annoying... But don't worry!! I'm here to help you, and at the end this review I will post a list of instructions for a proper following of the flowchart and routes!! Curiosity: As explicitly stated by Aiba in the game, Date has an extreme affinity for pornographic magazines and he becomes extremely excited when he thinks he sees a porno magazine, so much that his physical reaction time increases. This "special skill" is actually used in the game in a specific quicktime event So much more: AI: The Somnium Files is game with a very rich story, you'll get to learn about the character, what troubles them and you'll even be able to help them, all that while you investigate the mystery of the cyclops killer. The action moments with the quicktime events are always really cool and worth enjoying them, and this game is also full of humor and silly achievements if you step into Date's mind and act as silly. This is an awesome story that I recommend you experience by yourself, you won't regret. Come on detective!! Time to psync in the game!! πŸ” 🧠

Easily the best game I've played in 2023. AI: The Somnium Files is a mixture of a VN and adventure. You play Date, a detective who has lost his memories, only remembering the last 6 years of his life; he's been working for the police. His left eye was missing and replaced by an AI called Aiba; she helped him as a computer assistant and analyzed everything for him. One day, a murder was reported; when he arrived at the gory scene, to his shock, he recognized the woman and the young girl who was carrying the murder weapon. https://steamcommunity.com/sharedfiles/filedetails/?id=3111362909 The gameplay is like a visual novel mixed with Point&click, where you explore your environments, giving hints of what to do next. There are several locations to visit, some to explore, and others that are mandatory for the story. The character's development is phenomenal, I found almost all the characters are likable, even some of the villains. In some scenes, there is a QTE, which is unbelievably tricky if you use a mouse and keyboard like me. I highly recommend using a controller if you play the game. The most exciting thing in the game is the Psync, where you connect the main characters mentally and 'explore' their dreams; you get only six minutes to explore what is necessary to discover the following evidence and hints for the investigation. I found it a bit difficult at the beginning, but when I got used to using TIME wisely, I could finish each stage flawlessly. https://steamcommunity.com/sharedfiles/filedetails/?id=3109340400 I played the game in Japanese voice. The voice actors did a fantastic job, and I could say the same in English as I watched some people playing it on YouTube. The artwork, the characters' design, and the environment are beautiful, I enjoyed the soundtracks as well. In the menu, you get the chance to read the character's profiles, an appendix to all the terminology used, and an artwork album. Those you collect during the Psync if you finish it before the time is up. The story has many twists and routes to reach the true ending. Don't worry; you'll have to finish certain things and learn about the characters before the ending; there is no wrong route. And if you ever find yourself wanting to change some of your methods or choice of response, you can navigate the flowchart and choose which section of each route you need to reply to, either the story part of the Psync challenge. https://steamcommunity.com/sharedfiles/filedetails/?id=3111344070 Pros: +Interesting story with multiple twists. +Excellent writing. +Fully voiced (Choice between Japanese and English voice acting) +Interesting and likable characters +Good soundtracks. +Chellenging puzzles in Psync. +Multiple endings and routes. +Manual save. +Good game length. +Steam achievements. Cons: -There is a glitch in the Japanese voice ending, where the credit song will be in English. -QTE is tricky if you use a keyboard and mouse. A controller is highly recommended for the game. There are many funny and sad moments; each character nicely captures the emotions in the Japanese version. I encountered only one glitch throughout my gameplay where the ending credit song was in English instead of Japanese. Not a big deal for me. I highly recommend this game even at full price.
