This plot is insane. At times it feels like the writers are trying to extract my soul from my body. Playing this for extended periods makes my brain feel like it's melting out my ears. I cannot recommend this enough, 12/10.

Great game that gets dragged down by its god awful anime humour. Every 5 minutes they feel the need to add some terrible porn joke that it almost feels Pavlovian. The action scenes could be completely removed from the game and be swapped with a black screen that says "And then I beat everyone" that it would be better than whatever the game comes up with. But when they actually decide to take things seriously, it's quite a captivating story, made even better by its excellent soundtrack. The English Dub is also of very high quality. For the best experince, please go with the left cage when you get presented with a choice, and stick with it.

This game is wack. Like, hella wack Firstly, this game is genuinely insane. Looking at screenshots and trailers, you’d think it’s a really serious, deep, and thrilling game—and it is... eventually. What the trailers don’t show is that the game borders on comedy. For instance, the protagonist has superpowers that activate when he thinks about a certain adult magazine. Yes, this is canon—I’m dead serious. That said, this style of humor actually makes the genuinely good story, twists, and characters even more engaging in a weird way. The soundtrack, art style, and gameplay inside the somnium are top-notch. The visuals aren’t the best, but they’re passable. However, the facial animations could definitely use some work. But damn... the story is so good. It even managed to make me tear up, which is something the Zero Escape series never did. I’ve heard people say this game is better than Zero Escape, and for me, it’s on another level. I’d prefer this game over all Zero Escape games combined. I’d highly recommend this game to anyone who can tolerate some weird humor.

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!
