AI: THE SOMNIUM FILES - nirvanA Initiative raises an imporant question: What if we tried to make a game like the previous one, but completely squandered our pre-existing main characters in the process? Character assassination and unsatifying dynamics for the sake of a plot twist that's really just "Okay" compared to everything in ZE and previous AITSF should be illegal. However, the terrible things done by the narrative to Mizuki, Aiba and Date are compensated with a fantastic cast of new charactes. Ryuki and Taba knocked it out of the park. Sometimes I wish the game were just about them and didn't try to badly tie in our past lead for, idk, relevancy's sake. I genuinely don't get the vision. Still nice to paly. Just be emotionally prepared to not like certain parts of it if you really cared about the first one.
🛑 This is a real monkey's paw sequel. For everything they improve, two things are worse. If you really liked the first game, then this will have more of that (ish) - but be prepared to be a bit annoyed for a long time before the game clicks. They bet everything on an explosive endgame. The things leading up until then lacks that special spice that made the first game feel so nice... I think. ... Still, it's SOMNIUM. I can't NOT like it. (edit: play in japanese please) More precisely; [*] 💢 For some reason Anti-Aliasing is missing from the settings. Looks terrible. In many dialogue scenes the characters are standing so far away from you that their faces devolve into a pixelated mush. Even when people are relatively close, the jagged edges are very distracting. It's a bizarre choice to remove something so fundamental. [*] 💢 The way they structured the story makes the game feel nonsensical and illogical 90% of the time, until things suddenly start to make sense at that last 10% stretch. The fun twist ended up feeling less like the result of clever storytelling, and more like the game revealing that they've just been straight up lying to me in a confusingly straightforward fashion. Intentionally sabotaging your story for the majority of the game is just plain strange. I sorted the traces/flags under "bad writing" for most of the game. Towards the end of the Ryuki's line I dropped the game for a full week and only returned because "I had to at least try to finish it". For how fun the plot structure is after the fact, it's not too pleasant while you're up in it. [*] 💢 They're selling cosmetics that you can't even use! What the hell! You can both buy here on Steam or unlock ingame clothes and other gear for Tama and Aibo, but they won't actually show in-game until you've completed that section of the game... which means that you'll only see unlockables first after the game is over. Genuinely fraudulent. [*] 💢 Horadori. Originally I thought I didn't like the new characters much, but it was just Mr Unpleasant NPC George here overwhelming the measuring scales. He's got nothing going for him as a character. Unpleasant to look at, downright childish archetype, tedious to be around. Chieda might be bland, but at least he's not Horadori. [*] 💢 They still hasn't fixed the Auto-in-cutscenes problem. In scenes where the UI is hidden, the Auto setting is locked to whatever it was when you entered the scene. There are scenes in this game that are (and I kid you not) THIRTY FOUR MINUTES LONG. That's a lot of time to lock someone to the screen for. Why can't I pause, or just idk, click the button on my controller which toggles auto mode, and have it work ?... There's no indication for which mode you're in either - I have accidentally skipped dialogue because auto mode moved on just as I clicked Next. This shouldn't even be a problem in the first place... [*] 💢 The game crashed every now and then over the course of the story. Felt a bit icky, but wasn't a huge problem... that is, until I reached the epilogue and the game crashed every five minutes or so. Legit, 20+ crashes in one session. Not quite as stable as the first game. [*] 🤷 There's a lot of plain bad writing this time around. Part of it is due to the story being "structured in a creative way" (as mentioned previously), but there are also pieces of writing here that really take you out of the experience. Like Ryuki's monologue about his watch, for no apparent reason, to a person who should by all means already know. Or how they introduced those lines of text at the top of the screen, the fun facts newsflash stuff, to be used almost exclusively to inform you of things that you don't need to know, and which feels like the authors struggling to find a good way to inform the player of certain things, giving up and going "ah damnit just throw it on the screen". Same thing with the Wink Psync, which additionally make zero sense with how Psyncing has been described to work so far. Or how almost all the Somnium sections come straight out the blue, without any prelude - no arrest, no questioning, just straight to HQ in a very abrupt fashion (feels like date drug kidnapping rather than policework). [*] 🤷 Sometimes it feels like they forgot some important information from the first game. The kind of stuff that made the first game feel polished. Stuff like "Why does Aibo act stupid in Somniums but not outside"? Or how the prototype Psynch device works Or the relationship between ボダイ マモル and ABIS for that matter... [*] 🤷 I really don't think it was a good idea to include include NAIX. It just felt really stupid to have the mental ghosts of one character suddenly appear out in the real world. How they're introduced is terrible as well - you just waltz into their headquarters, just like that? Seriously? [*] 🤷 I was about to mention the mask until I read Aibo's trivia about it. Damn them for making it the funniest thing like that [*] 🤷 A loooot of things returning from the previous games. People, of course, but I'm talking about areas and music. Recurring jokes are good (sometimes) though. [*] 🆒 They made it so switching controller / KBM is automatic. You no longer need to switch in the launcher! Nice. (But that also means that all the glyphs are controller icons regardless of what you do, so I failed a few QTE:s just because I didn't know where "press down right stick" was on a keyboard...) [*] 🆒 There are more (and more challenging) puzzles in this game than the previous. They can be really fun at times, but they're handled a bit awkwardly - you're frozen, unable to save or look at anything other than the recent chat log, unable even to enter the menu or quit the game until you solve the puzzle. Sometimes you get access to important information that you then can't bring up when you solve the test. Bit ridiculous. I recommend taking screenshots of all the important clues you find. [*] 💚 The animations are SO MUCH BETTER this time! Fight scenes are actually kinda fun now. [*] 💚 Camera sections! キャメラ廻すぞ [*] 💚 Voice acting is stellar as always.
Super niche anime brainrot, but it's got solid W. They database patched the Somnium gameplay - now it's actual logic puzzles instead of the random trial-and-error BS from the first game. The new VR room-scanning mechanics are clean, and the AI sidekicks still roast the main characters flawlessly, carrying the comedy)))) Honestly though, they overcooked the main plot just for the sake of being "deep" and edgy. The game pretends to be a normal detective story for a while, until it starts throwing you across parallel timelines. The first game was a perfectly balanced masterpiece!, but this one is just doing too much. ... [url=https://store.steampowered.com/app/948740/AI_The_Somnium_Files/] the original is based and a must-play for everyone, but the sequel is optional - purely for the upgraded gameplay and signature unhinged humor. If anything, it takes more than 10 hours to finish. I was just too lazy to play it on my PC, so I played it on my “console”.
Im not sure if I would say its a perfect sequel due to mostly in my opinion the downgrade in date's character, Even if he isn't the protagonist in this game his character is pretty much just toned down to a perverted dude. Plot wise the game is even more stranger compared to the first. Love mizukis growth throughout the story along with 2 routes being set in different times respectively. Ryukis character felt a bit weaker compared to Date's and Mizukis character in both games. Also loved going to Atami Again.
