I learned Japanese by going into this game cold, looking up everything everyone said, and then adding each new kanji I saw into Ringotan which tests you on handwriting them from memory. I can now handwrite some 3000 kanji from memory, and comprehend an extremely high amount of Japanese. One of the best series for breaking into native Japanese media as a beginner, because it has voices on almost everything, a log you can replay all voiced lines from at any time, and a decent mix of dialogue and narration. Would I love it in English? Honestly, I don’t know. But as a learning tool, it’s absolutely perfect.

I feel like I have a good chunk of visual novels under my roster but I cannot believe that I did not pick up AI: The Somnium Files sooner. I would never have guessed in all my years alive that I would be actively praising a 30-year-old detective who is also a straight-up gooner.
I think it really excels when it comes to the layout of the story. It’s like getting a puzzle piece every time you progress the story but it isn’t until you have all the pieces that you truly understand what’s happening in the story. This game does a great job at taking itself seriously while also having really fun silly moments so that things aren’t so heavy. I do find that the pacing is a little slow at times, overall it was a really fun game and I would recommend it. They’ve got a great cast of characters, decent puzzles, and interesting dialogue.

this game sucks because it doesn't let me swerve date's car into oncoming traffic every time he says something stupid. loved every second of it though.

I bought this game due to a friend vouching for it. I was unsure at first, but now I can't stop thinking about this game.
While I trusted my friend's opinion, I was still skeptical. At first, I found it hard to resonate with the characters and its wacky comedic elements. I felt as if it was too jarring given the serious nature of the plot. I thought that I could never feel attached to the characters.
I was wrong. So very wrong.
This game was amazing. The characters are so memorable. I loved the story-telling and of course, the comedy. The characters were strange, but that's what made them all so memorable.
As for the main story, I did not expect such an intriguing plot. I was at the edge of my seat, wondering where the story would go and who was behind it all.
The gameplay is pretty standard for a visual novel, nothing to complain. Puzzles were at an appropriate level of difficulty. (Also please inspect EVERYTHING, you will get a lot of funny dialogue that adds more personality and life into the characters)
In short, please give this game a chance. It may confuse you at first, but stick with it. You will find yourself loving it.

Deeply stupid in places. Deeply sincere where it counts.
Kaname Date is the best protagonist ever.

I recently 100% completed AI: The Somnium Files on PC. It was a gift from a based, cultured friend—his taste is excellent—and I went into the game completely blind, knowing nothing about it or its creator. Only later did I learn that it was directed by the creator of Zero Escape, making this my first experience with his work. Overall, I can confidently say that I had a lot of fun with the game.
AI: The Somnium Files is a visual novel blended with third-person puzzle gameplay. It’s an interesting hybrid of two genres, one with clear potential to be expanded and refined further. The story follows Kaname Date, a detective suffering from amnesia, who investigates a series of murders alongside his AI assistant, Aiba. Using a specialized device, they can enter other people’s dreams to uncover clues, unlock memories, and piece together the truth. I really enjoyed this premise, and the characters are well-defined and genuinely fun to interact with.
Date is easily my favorite protagonist. His quirky personality and sense of humor make him stand out, and he carries the narrative well. The QTEs are surprisingly entertaining—especially considering the meme-worthy moments they produce. The English voice acting is also excellent and adds a lot of personality to the cast.
That said, the story is not without flaws. My main issue lies in how the “parallel worlds” concept is handled. It feels convoluted and messy, and ultimately unnecessary. The nonlinear structure and intentional vagueness of the narrative already work well on their own, so this element doesn’t add much and arguably complicates things more than needed. Still, the final mystery reveal is strong and satisfying. These issues aren’t major, but they are worth pointing out.
From a production standpoint, the game’s low budget is noticeable. The environments are limited, and there is a lack of character model variety. This becomes especially apparent during the Somnium (dream) sections, where it feels like the developers may have run out of resources. I would have loved to see more gameplay variety overall. For example, a hub world where Date could freely move around, or more investigative mechanics where Aiba could be used for scanning and other creative interactions. Taking some inspiration from Danganronpa’s hub-based structure could have worked really well here.
As for the Somnium sequences themselves, while the concept is great, the execution could have been more ambitious. Since these sections take place inside a person’s mind, the developers had an opportunity to go fully surreal and experimental. The Minecraft-inspired Somnium shows glimpses of this potential, but I wish more dreams had embraced that level of creativity.
Hopefully, these issues are addressed in future entries. Despite its shortcomings, AI: The Somnium Files is a fun game with a solid story and memorable characters. The gameplay is decent but clearly in need of refinement. Overall, I’d give it a 7.5/10.
