  • Fast-paced, fluid, and satisfying combat with fun party-based skills and abilities.
  • Movement and exploration enhanced by unique Monstrum gifts like wall-running, gliding, and teleportation, turning the city into a vertical playground.
  • Engaging story with well-written characters and meaningful character development, including strong connections to previous Ys games.
  • Setting is mainly a gray, drab prison city with repetitive environments and limited color variety, leading to a lack of visual excitement.
  • Story pacing can be uneven, especially slow start with heavy dialogue and side quests that feel like filler or mandatory grinding.
  • Combat and gameplay can become repetitive with some exploits like healing items making battles too easy, along with some awkward controls and poorly designed tower defense segments.
  • story
    856 mentions Positive Neutral Negative

    The story in Ys IX: Monstrum Nox received mixed reviews; it is praised for intriguing characters, emotional arcs, and a gradual buildup with engaging twists mostly in the latter half, but criticized for slow pacing, excessive and mandatory side quests, and a muddled, sometimes predictable plot. While it benefits from strong character development and thematic depth, many find its narrative less compelling and cohesive compared to Ys VIII, with the story often overshadowed by repetitive missions and filler content. Overall, the story is seen as decent and worth experiencing, especially for fans familiar with the series, but considered weaker and less impactful than previous entries.

    • “The story had an odd edginess to it though it was overall good, and I was a fan of most of the cast and how they grew through the story.”
    • “First, the main characters have way more depth (it probably helps that each gets a chapter just to themselves) and the story certainly benefits from it too.”
    • “The story is interesting and keeps you guessing, while the characters are fleshed out and distinct.”
    • “The game suffers heavily from the way the story is laid out, with the first six chapters of the story, that being the first 30 hours of the game, all playing out the same way: you do some sidequests to get nox points, you grind battles in the city to get the remaining needed nox points, then you do two raid battles to open up new areas with one being mandatory and the other optional.”
    • “If you want a disjointed clown plot that appears to be three separate plots - a plot about helping the cashier at hot topic fight hot topic Christmas tree ornaments in a parallel dimension, a plot about a wacky alchemist, and a plot regarding the city politics whose "message" sincerely appears to be "the oppressive, foreign, occupying authority poisoning a third of the city and treasonous collaborators working for same = good, actually, stop complaining and worship authority because this game was made in Japan" - that get haphazardly smashed together in the last 2 hours, then I cannot recommend this game enough.”
    • “The story is just atrocious - the amount of plot holes in it is just overwhelming...”
  • gameplay
    401 mentions Positive Neutral Negative

    The gameplay of Ys IX largely builds upon the well-received fast-paced, action-oriented combat and exploration mechanics established in Ys VIII, adding new traversal abilities like climbing, gliding, and wall-running through the city environment. While many appreciate the refined, fluid combat system and the introduction of character-specific "gifts" that enhance movement and combat variety, some critics note the formula feels familiar with few major innovations and that gameplay is frequently interrupted by excessive dialogue. Overall, it offers an engaging, polished action RPG experience especially for fans of the series, though it may feel repetitive or less fresh to those seeking groundbreaking changes.

    • “Gameplay amazing, so fluid and chaotic as we all love in this series.”
    • “The gameplay is outstanding, the characters are endearing, the English dubs and localization are fantastic, the story is serviceable, there's tons of stuff to do and collect, the movement/exploration is a blast, and this is an excellent PC port.”
    • “Falcom managed nonetheless to provide an incredibly entertaining game by refining the already stellar gameplay from Ys VIII and adding a great freedom of movement, unparalleled in the series, that allows to move Adol at high speed all over the city of Balduq, this opus' new setting.”
    • “Dislikes: too much dialogue and not enough combat, too many mechanics copied exactly from Ys VIII even when they don't make sense for this game, status ailments can be ignored even on hard mode, resources less plentiful than past games, too many characters, feels claustrophobic due to lack of true open world, plot is too cryptic: I'm 50 hours in and still don't know what's really going on in the game world, characters are not endearing like Ys 8.”
    • “The world isn't as fun to explore as previous games, the story is muddled and confused in its message (saving the town is noble, but challenging the oppressive regime controlling it is portrayed as negative?), and the gameplay is almost entirely mind numbing button mashing.”
    • “The kinetic gameplay is frequently interrupted by heavy-handed narrative segments and unskippable dialogue.”
  • music
    245 mentions Positive Neutral Negative

    The music in this game, crafted by Falcom Sound Team jdk, is widely praised for its energetic guitar-driven rock style and variety, delivering a standout soundtrack that enhances combat intensity and game atmosphere. While many fans consider it a strong and memorable addition to the Ys series, some critics find it less impactful or consistent compared to previous entries like Ys VIII, with a few tracks seen as forgettable or not fitting the game's tone. Overall, the soundtrack remains a highlight, fitting well with the fast-paced gameplay and often elevating the experience despite some divided opinions.

    • “The soundtrack, composed by Falcom Sound Team JDK, is once again a standout feature.”
    • “From pulse-pounding battle themes to moody exploration tracks and emotional story pieces, the music is diverse and deeply integrated into the experience.”
    • “Fans of previous Ys soundtracks will find much to love here, with compositions that elevate both the intensity of combat and the atmosphere of the world.”
    • “The plot was weak, the soundtrack was weak, the characters were weak and generic, and the main heroine was a disappointment.”
    • “Last but not least, the soundtrack... oh boy, Falcom has lost their spark with the music department, the bangers are still there, but there are fewer, way fewer, even Celceta had better music.”
    • “The soundtrack in some instances is awful, and in other cases just barely okay, in no case did I ever find it memorable however.”
  • graphics
    153 mentions Positive Neutral Negative

    The graphics of the game are generally considered outdated and modest, often described as below contemporary AAA standards with a drab, grayish aesthetic and limited improvements over previous series entries. While character designs and certain visual elements receive some praise, many reviews note that the visuals lack vibrancy and polish, but the game runs smoothly with good optimization. Overall, although the graphics are a common criticism, they do not significantly detract from the enjoyable gameplay and story experience for most players.

    • “Graphics are beautiful, that's for sure, music is not disappointing, and once you 'crack the code' of how to explore, finish missions, and just continue the story, the game is actually enjoyable.”
    • “Ys IX improves on Ys VIII with better graphics, tighter movement (grappling, double-jump, flying), detailed character designs, clearer collectibles, voiced and varied NPCs, useful quality-of-life fixes, strong BGM, and good voice acting, while suffering occasional clipping, noticeable aliasing at 1080p, no swimming, and a frustrating requirement to have saves from Ys Memories of Celceta and Ys VIII to get some cross-game rewards.”
    • “This is the best looking game in the Ys series so far with stunning graphics.”
    • “Poor graphic/character models, jesus what happened here?”
    • “Not only the graphics are atrocious but also the art-style, it's the most dull and amateur thing I've seen in quite a few years, and that alone speaks volumes of how much (or should I say little?) they cared about this game.”
    • “Feels... weird, like, really weird, I know that Falcom isn't a top-tier studio when it comes to budget, but legit felt like I was playing an early PS3 era game with some upscaled graphics, like, everything feels... floaty and dead?”
  • optimization
    48 mentions Positive Neutral Negative

    Optimization is generally strong on PC, with smooth 60fps performance and extensive graphical and performance settings allowing good scalability across systems, though some users report occasional frame drops or stuttering in demanding areas. Ports demonstrate solid optimization with minimal bugs, thanks in part to experienced teams involved, but high-end hardware is often recommended for consistent highest settings. Console versions tend to underperform compared to PC, and visuals are noted as modest, which helps maintain performance despite large environments.

    • “However, the game runs smoothly and is well-optimized on Steam, with options to tweak visuals and performance for a variety of systems.”
    • “Performance is great, and there are plenty of PC-specific settings to fiddle with along with a custom config file if you really want to fine-tune things.”
    • “The port itself is great, with a wealth of options and solid optimization such that you'll only have trouble running it if you blatantly ignore the settings menu telling you which options will have a significant performance impact.”
    • “Plus, the optimization is absolutely terrible, I can run quite well pretty much every modern AAA game with decent graphics and 60 fps, but this?”
    • “Character models and environments simply are not detailed enough to justify the performance difficulties many people will have with this game.”
    • “⚠️ Stuttering in the cities even with an RTX 3090 & 5950X.”
  • grinding
    46 mentions Positive Neutral Negative

    Grinding in the game is a mixed experience; while some players find the early sections tedious and the resource farming repetitive, others appreciate that grinding often ties directly to meaningful progression and unlocks useful bonuses. Crafting and material gathering can feel unbalanced or underwhelming, with certain sequences like base defense or nox farming becoming monotonous. Overall, despite some grind-heavy moments and mandatory errands, the game generally balances grinding with enjoyable exploration and story elements, making it feel less taxing than previous entries in the series.

    • “Little to no grinding though you definitely can if you want to; fighting higher level enemies will exponentially increase the XP you receive and leveling skills is absolutely not necessary, it's just there as a bonus for those who want to.”
    • “45 hours with almost all achievements on hard difficulty (the ones missing you get by replaying the game), it was a bittersweet experience. The first half of the game is really tedious, you are just trapped in this city, going against all my expectations to explore a nature-like open world (like the prequels).”
    • “The bonus stats you grind carry over, so the time spent grinding isn't completely wasted.”
    • “The open world is fun to explore, but it is a little light on activities besides grinding for the nox gauge and the handful of side quests.”
  • character development
    34 mentions Positive Neutral Negative

    Character development in the games receives mixed reviews; while many praise the vibrant character designs, individual arcs, and solid voice acting that enrich the party members, others feel the development is rushed, unevenly distributed, or lacks depth compared to previous titles like Lacrimosa of Dana or Ys VIII. Some find characters stereotypical or cartoonish, and story progression sometimes overshadows meaningful growth, though overall the series maintains an enjoyable balance of story and character appeal.

    • “Good character developments on the six party members, each having their own arcs.”
    • “You'll see a lot of character development from the entire roster throughout your adventure in Balduq.”
    • “The characters are somewhat stereotypical, but there's sufficient character development to make them appealing.”
    • “The character development is really bad.”
    • “I think they should've spread the story and character development points across the chapters instead of putting everything into the end, and because of this some of the characters felt undeveloped or completely forgotten after they reveal their true identities/backgrounds.”
    • “I personally felt, with the exception of Anemona and Credo, that the character development took a steep backseat in this one compared to Ys VIII, where almost everyone was focused on quite well.”
  • emotional
    33 mentions Positive Neutral Negative

    The emotional aspect of this game is mixed, with many praising its touching storylines, well-developed characters, and impactful finale that evoke genuine feelings, especially for longtime fans. However, some find the narrative slow, less engaging, or overshadowed by gameplay interruptions and side content, making emotional attachment uneven compared to earlier entries like Ys VIII. Overall, the game offers a mature and heartfelt experience, though it may not reach the same emotional heights as its predecessors.

    • “The monstrums each have fully fleshed-out backstories, personalities, and emotional arcs, which are revealed gradually as the story unfolds.”
    • “The strongest theme in the story is family, which is a throughline across all of the party members' personal stories (and quite a few of the named NPCs), and some of the moments with these characters are genuinely touching.”
    • “Voice acting is very well done and fits the emotional context of scenes perfectly, with each voice actor clearly having put work into portraying their character rather than just reading the lines.”
    • “It feels like they tried to mix Trails and Ys, resulting in a game with a good gameplay core weighed down by a boring story and useless dialogue.”
    • “The lackluster areas and boring story couldn't be saved by good combat.”
  • atmosphere
    20 mentions Positive Neutral Negative

    The atmosphere in Ys IX: Monstrum Nox is praised for its cohesive, moody, and gothic design that effectively shifts from the bright island vibes of previous entries to a darker, prison-themed setting. The soundtrack strongly enhances the ambiance, blending intense and atmospheric compositions, though some find the environment visually tiring and occasionally mismatched with the music. Overall, the game delivers a bold, immersive atmosphere that fans of the series appreciate, despite some critiques of its repetitiveness and dated feel.

    • “Ys IX: Monstrum Nox trades the bright island vibes of VIII for a darker, more mysterious atmosphere, and it absolutely works.”
    • “Ys IX: Monstrum Nox is a bold and atmospheric entry in the long-running Ys series, taking the franchise in a more experimental direction while retaining its signature action-RPG roots.”
    • “The story keeps you guessing, and the setting—part gothic city, part twisted dimension—is dripping with atmosphere.”
    • “The atmosphere is cohesive and moody, fitting the "prison" theme, but it eventually becomes exhausting to look at.”
    • “Both figuratively when it comes to how formulaic the overall structure and progression of the entire game are, and literally when it comes to the actual atmosphere and environment of the extremely gray prison city of Balduq.”
    • “The game tries to express dread and a spooky atmosphere with upbeat music and that doesn't work at all.”
  • humor
    9 mentions Positive Neutral Negative

    The humor in the game is generally well-received, with characters like Hawk providing sharp, sarcastic, and self-aware jokes that enhance the experience. Many players enjoy the quirky and playful interactions among diverse characters, though some find certain comedic moments overly cutesy or lacking subtlety. Overall, the humor adds charm and personality, especially appreciated by fans of JRPGs with a lighthearted tone.

    • “I initially hated Hawk (the hyper-aggressive, hyper-cringe, edgelord party member), but he quickly grew on me with his amazingly blunt, sarcastic, hilarious callouts and general self-awareness.”
    • “For instance - White Cat is lovely, Doll is hilariously and adorably weird, Raging Bull is always fun to tease, combined with Hawk being cheeky in the back, the weird Mister with “maii-tii-nii” saying every time, the investigator with “preposterous” moments and more.”
    • “The characters are well written, battle system is great, exploring the town is funny and the story is really cool.”
  • replayability
    9 mentions Positive Neutral Negative

    Replayability varies across games, with some titles offering strong incentives like new game plus and evolving content, while others lack features such as bonus dungeons, multiple endings, or gameplay modifiers, resulting in limited replay value. Games praised for high replayability often include multiple endings and additional modes, whereas those with linear progression and repetitive gameplay tend to have lower appeal for repeated playthroughs.

    • “Yeah, I love the series. Great replayability (New Game Plus) and evolution. I prefer the location of Dana, hope for Nordics. Meanwhile, get it on sale.”
    • “Has replay value for sure.”
    • “Ghost of Tsushima had a very high replay value and that's where most of those hours of playtime come from.”
    • “With the lack of bonus dungeons or optional NG+ modifiers like infinity mode, changing party size that enables solo play, Ys IX’s replayability is also a lot less.”
    • “Monstrum Nox has about 40 hours of playtime to full completion including collectibles and all side quests with repetitive gameplay and really no replay value aside from a couple years down the road if you ever get the urge to fire it up again.”
    • “This one only has one ending too, so that's another step down from previous installments as well, deleting any replay value.”
  • stability
    2 mentions Positive Neutral Negative

    The game port is highly stable, running smoothly without crashes, FPS drops, or technical issues, and the developers are actively engaged in troubleshooting support.

    • “The port runs great with no crashing, FPS drops, or any technical glitches!”
