The best visual novel I’ve ever read; with every completed route, the mystery grew deeper and my curiosity to uncover the truth just kept growing.

The Game Is Truly Worth Playing............. The Story Is Good with unexpected Twist <3.The Action is Truly Horrible To be Honest Did not Like action...

Kotaro Uchikoshi. A name synonymous with unique cult classic sci-fi visual novel adventure games with crazy plot twists. Though I never became a huge fan, I personally liked playing each of the Zero Escape games (999, Virtue's Last Reward, Zero Time Dilemma), and when I saw the first details and videos for this new project--A.I.

Kotaro Uchikoshi. A name synonymous with unique cult classic sci-fi visual novel adventure games with crazy plot twists. Though I never became a huge fan, I personally liked playing each of the Zero Escape games (999, Virtue's Last Reward, Zero Time Dilemma), and when I saw the first details and videos for this new project--A.I. The Somnium Files--I knew right away that I would like playing this one too. 2019 wasn't an exciting video game year for me, but this was a title that stood out as something I'd want to play as soon as I got a Switch (more specifically, a Switch Lite). Of course this one's on PC and PS4 as well, but I prefer reading VNs (or playing games with tons of text) on handhelds.

Somnium Files works with a concept I really enjoy in fiction -- entering people's mindscapes or dreamworlds (as in the film Inception, or the video game Psychonauts). In this case, your protagonist is a detective for a secret police force that uses a device that allows him to uncover truths hidden away in suspects' minds (in hopes of solving a big murder mystery). How this plays out isn't the best to be honest... You control a cute A.I. girl companion who walks around in the dream world, and your goal is to bypass "mental locks" -- what this means is you need to go up to random objects, select something random for your character to do, and hope that it makes the right random things happen that advances the dream the exact way the game wants it to. Unfortunately most of the dreams are just variations of crime scenes, and much of the puzzle-solving doesn't feel intuitive. You also are on a strict time limit, so you don't even really get to explore the dream worlds much. I'm not sure what would have been a better way to go about all this, but I mostly just felt "okay" about it at best (which is a shame because again, I love this concept). I ended up using a guide for the second half of the game.

For the story itself, I'll start with the strong points. First, the characters. Uchikoshi has definitely improved his storytelling in this particular department. Somnium Files has a very memorable cast, and the protagonist in particular is a rather likeable and amusing fellow with strengths and weaknesses (and he's hot, I'll throw that out too). The other significant strong point is this game's presentation. This is definitely the slickest-looking VN adventure game I've ever played. The UI, the environments, the character models, the menus, the way you can look around while holding conversations, and the way other characters in the scene react to what others are saying--it's all a huge step above so many other games in this sort of genre. I consider it the new gold standard.

For negatives, well it's mainly just the actual gameplay portions of the game, which didn't do much for me. I also feel that the story overall is just... good. Which is fine of course, good is good. But I think fans of Zero Escape will want to be careful about how much they'll expect of this one in terms of crazy plot twists. There are big reveals, but they are not nearly as big as the ones in Uchikoshi's previous games. Somnium Files is working on a much smaller scale with its more focused (and more familiar) murder mystery-style narrative, which again, I'm down with. I'll also mention though that the tone for this game is something of a mixed bag for me. I personally was fine with the game including silly and lighthearted scenes to shake things up a bit (and help flesh out the characters more) -- but the game's kooky blend of humor gets repeated several times throughout the story. For me, it just got old after a while.

So I still haven't been fully won over by any of his works yet, but I also can't help but remain eager to check out whatever game Uchikoshi works on next. Like Somnium File's protagonist (and multiple other characters), I may be just a little tsundere.

Pervy sense of humour with a story that will captivate you

AI was a game that stuck with me from start to finish. Although they did leave alot of hints throughout the journey that you eventually picked up what as going on as well as probably figured out the twist, it was well worth every minute playing this adventure.

If you are not into perverted/boob sense of humour though, 100% steer-clear …

If you are not into perverted/boob sense of humour though, 100% steer-clear of this game as you will just find it irritating while I absolutely loved it and had a blast laughing my way through.

Finally hit the big twist. It was predictable but a lot of fun. If this had been at the midway point and maybe hinted at more subtly it could have been a really WOAH moment but this late in the game it felt more like, oh good he finally figured it out.

I'm still enjoying the game but plot wise it does feel a little like Uchikoshi wrote this game for people new to his work instead of returning fans because anyone who has even read any serious amount sci fi stories ought to be able to predict where this is going way earlier. It also feel painfully linear compared to his other games. Even ever 17 and never 7 have a lot more freedom. It's good for what it is and the voice acting and motion capture is ACES in a lot of places but it just feels like this game is a lot more style over substance compared to his Zero Escape trilogy.

Just finished the Mizuki route. So far it's good but not great.

Just finished the Mizuki route. So far it's good but not great. There haven't been any really crazy twists so far, the premise is interesting but inherently less gripping than a locked room escape mystery. There's a real lack of tension with our characters effectively having cartoon superpowers whenever the plot demands but not at other times. The character interactions make me smile and are heartwarming but the abundance of sex jokes is a little too much even for me, and there are a lot of weird out of character moments where the characters stop being themselves and become mouthpieces for uchikoshi to talk about something he wants to regardless of if it fits in or not, but that's pretty par for the course on his work.

Overall I'm interested to see where this goes but without that locked room premise urging him forward I feel like the story is meandering a good deal.

Oh and side note the lack of any meaningful gameplay is kinda a downer. There are almost 0 meaningful choices in the game and no puzzles. Remember that mobile port of 999 every got sour on because it only kept the door choices and nothing else? This game plays a lot like that. There are so few choices that I just set it to autoplay and listen to it in the car on my way to work. I have gone 40 minutes without needing any significant input before.

Off to a great start! A little less gameplay than I would personally like but the interactions are super charming!

It's really a 3.5, but this website apparently won't let me do that. It dragged a lot and it's comedic timing felt off sometimes, but the payoff was well executed and worth it.

Fell off this game hard. The "quirky"/"trash anime" aspects of it, mostly the humor, tone, and some of the characters are off-putting. The story is kinda interesting at times, and I actually do like a couple of the characters and their designs, but it's just not holding my attention.

Fell off this game hard. The "quirky"/"trash anime" aspects of it, mostly the humor, tone, and some of the characters are off-putting. The story is kinda interesting at times, and I actually do like a couple of the characters and their designs, but it's just not holding my attention. It feels like it's trying to dive deep into the cool pseudoscience that Zero Escape had, but to me it's coming across as forced this time rather than cool. The fact that the story branches off feels obligatory, like they only did it because their last games did it. At least the Zero Escape games had substantial interesting puzzle gameplay aspects, but this game's gameplay sections are really lacking (I guess that's a nice way of saying "bad") and 95% of the game is just clicking through until you've exhausted all available conversation starters and moving on to a new location. There's potential to the detective aspect of this game but it's handled so superficially. It feels like there would be some payoff for getting through to the end but I just can't get into it.
