- Accidental Innuendo: beatmania IIDX 23 copula is meant to refer to the Latin word "copula", meaning "bond" or "connection" (think "couple"), but English-speaking fans got a giggle out of the fact that it sounds like "copulate".
- Breather Level:
- Elisha on SP Hyper is level 10, but is laughably easy for one; it's an easy 9 or a difficult 8 at worst. While this could be excused as the development team overestimating how difficult Charge Notes would be at the time, the rating has never changed since the chart's debut and many charts with Charge Notes since have gotten more accurate ratings.
- TOKAGUSHI's SP Another chart, a 12, is also not as difficult as other boss charts, for mostly the same reason as Elisha. Considering how Echidna's SP Another chart is a 12, debuted in the same game and also uses quite a few hold notes, it's becomes more noticeable.
- Broken Base:
- INFINITAS. Some dislike the very limited songlist (so far, it mostly just consists of songs from beatmania IIDX 17 SIRIUS) especially in conjunction with the subscription fee of 1598 yen per month. Others are just glad that Konami finally put out a new consumer version of IIDX after six years—on a platform that's very easy to port IIDX tonote , to boot—and are hopeful that they will eventually expand the songlist to make it worth the cost.
- The songs removed from one style to another tend to upset fans, since instead of focusing on songs that fan don't like, Konami focuses on songs by artists that no longer work for them. Music by Slake, Naoki and Akira Yamaoka are few and far between.note
- Is Single Play 8th Dan really easier than 7th Dan? Or are players just not practicing properly?
- DJ Sharpnel's contributions to the series tend to be extremely polarizing, a far cry from the duo's usual works.
- Complacent Gaming Syndrome:
- In Japan, very few players at the highest levels will actually use the normal Groove Gauge, as many players, if not focusing on score, focus more on getting Hard and EX Hard clear as well as a Full Combo than on basic clears. In fact, it's more common for players to use Easy and even Assisted Easy gauges than the normal gauge.
- From roughly 8-dan onwards, most Single Play players always use the Random modifier, as it forces them to learn new types of patterns and also makes some charts easier to play depending on how the RNG feels.
- Crowning Moment of Awesome: Hoshino Kanako kicking ass in Answer's video.
- Crowning Music of Awesome: Has its own page.
- Cult Classic: IIDX, while not a commercial success outside of Japan due to its lack of exports, is one of the most talked-about games in English-speaking BEMANI communities due to its long 25-game history, high skill ceiling, and focus on Simple, yet Awesome controls and interface.
- Disappointing Last Level:
- Many players feel this way about some of the boss songs, feeling that they were designed more to fit their respective charts with less regard for track quality. Thor's Hammer, DIAVOLO=], and Elemental Creation are a few such examples.
- The final unlock of tricoro's "Our War of the Worlds" event, which appears to be the game's final unlock event, runs on a lifebar that is damaged every time the player plays through the game. Fortunately, the lifebar was shared by all players on the network. Unfortunately, not only was the unlock tedious, taking many days to unlock even just the Normal chart, but the unlock song itself, Kyatorare Koi wa Mo~moku, is a cartoony "denpa" song that many players consider to be highly annoying, or at the least, not fitting as the Final Boss song of tricoro.
- Discredited Meme: Due to abuse, the "Himiko? FUCK THAT SHIT!" meme (see Memes.BEMANI) is largely seen as this today.
- Ear Worm: Well, obviously. The song "smooooch・∀ ・" in particular has spawned its own addictive internet meme on Nico Nico Douga.
- Ensemble Darkhorse:
- SigSig and the "smooooch・∀ ・" princesses.
- Rche, who many fans find to be exceptionally cute and feminine for (a character commonly perceived to be) a boy.
- Even Better Sequel: While new installments are generally well-received, tricoro is seen as a brilliant overhaul of the game interface.
- Fan-Preferred Couple: Rche is often paired up with fellow Lincle Kingdom characters Cuvelia or Ashemu. Or both at once.
- Fandom Berserk Button: Watching an unlock system cutscene in the arcade with people waiting to play? Don't you dare stop to watch them, even if you can understand the dialogue, or someone will forcibly press Start for you to skip it.
- Fandom Rivalry: Many players of IIDX tend to look down upon many other rhythm games for having lower skill ceilings. Conversely, players of more casual rhythm games decry it for its high barrier to entry.
- Game-Breaker: On a song with scale notes, using the Random modifier to rearrange the notes tends to make the chart easier.
- Germans Love David Hasselhoff:
- SLAKE's minimalist, atmospheric and traditionally occidental output specifically endeared him to western audiences during his time as a BEMANI composer.
- The game has a higher proportion of fans amongst BEMANI fans in the West, partly due to IIDX being one of the first arcade rhythm games other than DDR to be (unofficially) exported across the Pacific. In Japan, it has to compete with many other rhythm games that are either infeasible to export to or aren't as high-demand outside of Asia, such as jubeat and CHUNITHM.
- Hilarious in Hindsight:
- The 2009 horror novel Another, which features a protagonist named Mei.
- "Salamander Beat Crush mix" from beatmania 2ndMIX, which samples Starfield from Salamander / Life Force and then segues into a completely different track, is the original SiIvaGunner high-quality rip.
- No folks, Wow Wow 70's is not a disco arrange of the 2013 Reflec Beat song Wow Wow VENUS.
- It's Easy, So It Sucks: Not the game itself, but some players of this who are very high-tier find it difficult to play other rhythm games due to their comparatively low skill ceilings.
- It's Hard, So It Sucks: Half of why this game is largely inaccessible to rhythm game newbies is the harsh learning curve and the intimidating high-end charts that can scare players away from trying the game. (The other half is that the game has next to no licensed tracks.)
- It's the Same, Now It Sucks: The kaiden courses for PENDUAL are exactly the same as SPADA's, much to the disappointment of many players.
- Memetic Badass: IIDX player DOLCE. has become something of an idol amongst many players.
- Memetic Mutation: The IIDX fan community has its fair share of memes, from worshipping a song to "TWO DEE ECKS GOOOOOOOLD", and then some.)
- Himiko? FUCK THAT SHIT! PABST BLUE RIBBON!
- GET IT!?
- "Is 69 easier with Hard on?"Explanation
- There's actually a bit of a running joke amongst certain IIDX communities in both Japan and the west that Bemani and Pepsi (and occasionally other soft drink manufacturers) conspire to create new color-coded flavors for each installment. Every subtitled style has a flavor of Pepsi (or Mountain Dew in some cases) that seems literally made for each other; it has extended to other Bemani franchises on occasion, such as Pop'n Music with Carnival-flavored Pepsi...
- Red Zone remixes.
- "SigSig" and smooooch・∀・ have seen many parodies of their iconic videos, especially on Nico Nico Douga
- Dai, the male dancer who prominently appears in HHH songs such as So Fabulous !!
- The "SOMEBODY SCREAM!" and "1-2-3-4-5-6 DO IT" samples became slight catchphrases too.
- SP 7th Dan and "THE SAFARI" are notorious amongst players trying to go up from 6th Dan, and there are players who can't do 7th Dan but can clear 8th Dan; these players are known as "Safari Refugees".
- More Popular Spin-off: Of the three series with the beatmania name, only IIDX is still ongoing.
- Narm: Even by the standards of oddball IIDX titles, CANNON BALLERS sticks out like a sore thumb due to just how silly it sounds, not helped by the logo of the game not only lacking any actual cannons or cannon balls but also having a motorsports theme. Fans both in and out of Japan scratch their heads wondering just what the heck cannonballs and auto racing have to do with each other.note
- It might be referring to Cannonball Run.
- Narm Charm: A couple songs are liked by the Western fandom for their So Bad, It's Good Engrish:
Walking with you on a happy sunny day
- DJ Yoshitaka's remix of Ghostbusters retains the original English lyrics, but with hilariously bad pronunciation. Foo you gone car?
- Poodle due to its lyrics, which are in hilariously broken English and are displayed karaoke-style in the video. A sample:
you know me clever more than retriever
Washing me everyday tidy neat
you know me precious dog as a dynamite
Believe in me
If it's rainy again
Nobody wanna cry
Nice cow bone you are my lover
I like dubstep!
- BroGamer is practically built around this. It is littered with cheesy gamer lingo, and the genre is "Super Ultimate Hyper Core". It is also a very kickass song.
- Newer Than They Think: A number of songs, most famously A, AA, Scorpion Fire and any of Osamu Kubota's songs, despite sounding classical, were composed specifically for the series.
- Nightmare Fuel: Like other BEMANI games, it has a decent share of it.
- Play the Game, Skip the Story: Starting in tricoro, cutscenes accompany the unlock events. Most players skip them, especially outside of Japan as the cutscene dialogue is not translated. Taking your time to read the dialogue will likely prompt other players to press Start for you to skip the cutscene.
- Scrappy Mechanic: Like with many other BEMANI games, a stage failure in Standard mode ends your credit immediately afterwards unless it's a level 6 song or lower or you use a DJ VIP PASS, which either requires farming V-Discs by playing or using PASELI, neither of which are available if you are playing the game in the US. As a result, you're forced to play easier songs for your first two stages (three if Extra Stage is enabled) just to get your money's worth, only going for songs you're not sure that you'll clear on the last stage.
There are modes that guarantee you get all of your stages without having to use Asia-exclusive features but they all come with catches: Free mode guarantees all stages but only two are given to you, Free+ mode guarantees 3 stages but is only available in a 2-player game (which additionally means it's unavailable for Double Play), Step Up mode guarantees 3 stages but limits what songs you can play, with none of the songs available being songs that debuted in the current version, and Hazard mode guarantees 4 stages but instantly ends the current stage on a combo break.
As a result, IIDX is one of the few Rhythm Games with a top-end playerbase that actually uses "easy mode" options (specifically the Easy and Assist Easy gauges) with some degree of regularlity, because they'd rather endure a bit of Easy-Mode Mockery that doesn't influence their scores anyway than blow an entire credit on stage 1 or pay extra just to ensure they get what they paid for. That's right, IIDX is so Nintendo Hard that serious players are willing to turn the life difficulty down!
- Sequel Displacement: IIDX is so widely popular among BEMANI fans that it's not surprising to see IIDX players who have never played the original 5-key beatmania.
- Sequelitis: 9th Style, the first IIDX game to use Windows-based hardware, is riddled with timing problems, as well as a Game-Breaking Bug in which attempting to play the song "quasar" will sometimes crash the game. However, these issues appear to have been ironed out in 10th Style.
- Additionally, 9th Style is notorious for charts with song-ending Difficulty Spikes. While this sort of gimmick is common throughout the serious, it's very much pronounced in 9th Style charts, to the point where some players use Hard Gauge to circumvent the 80% Grooge Gauge requirement.
- Polished Port: 9th Style on PS2, which not only looks prettier than its predecessors and runs at a higher resolution, but also doesn't suffer from the same timing problems that its arcade counterpart is infamous for.
- Signature Song:
- Mei and Nageki no Ki, simply for being two of the hardest charts in the series (not counting Black Another or ✝LEGGENDARIA charts).
- For players between 6th Dan and 8th Dan on Single Play, THE SAFARI simply for being the reason most players can't upgrade from 6th Dan to 7th...or pursue the Safari Refugee life and skip straight to 8th Dan because they find it easier.
- "Stop Having Fun" Guys:
- Don't you dare admit that you use the Random modifier on scale-heavy charts. Strangely enough, the opposite applies for all other charts once you're at the level 10-and-up range: Don't you dare admit that you don't use Random.
- Using Assist modifiers and even just having the purple Assist Clear lamps on charts tends to draw mockery from some players.
- Averted with regards to the Easy and Assist Easy modifier amongst Japanese players, the rationale being that when you're practicing charts you don't want to throw away an entire credit from failing one, and there's more emphasis on score than non-Hard and EX Hard clears anyway. While DJ VIP Passes exist so you can be guaranteed three stages, they do cost extra PASELI on top of what you pay for one credit.
- Suspiciously Similar Song:
- FIRE FIRE appears to be a Jimmy Hart Version of "Russian Roulette" by Bazooka, and it's easy to tell.
- Round and Round shares a lot (almost the same song, in fact) with composer Masayoshi Minoshima's earlier work, the more famous Bad Apple!
- Tastes Like Diabetes: Many of the more pop-ish songs in the franchise will inevitably have videos with this trait. Empress as a whole could also count as this, although thankfully it wasn't as bad as many thought it would be.
- Except for I'm Screaming LOVE.
- That One Attack:
- CONTRACT's SP Normal stage is generally around the difficulty of a level 7 chart...right until the very end which throws a series of mini-scales combined with scratches. It is ONLY because of this part that the chart is rated a 9, making it one of the three highest-rated Normal charts (the other being Sense 2007's and gigadelic's).
- The end of The Dirty of Loudness' SP Another forces you to hit all 8 notes at the same time several times. It also makes a return in reunion.
- That One Boss:
- For those clearing out level 9 songs, Watch Out Pt. 2 is particularly frustrating, thanks in no small part to the abundance of scratches.
- THE SAFARI, notorious for dashing the hopes of those trying to achieve 7th Dan and having been the final song of the 7th Dan course for many versions now. It's to the point where some players will just skip straight to 8th Dan, finding even "gigadelic" on Hyper (which by the way is rated a 12note ) to be easier than THE SAFARI.
- G2 on Normal is no slouch for a level 8 due to the masses of drumrolls near the end of the chart; there are plenty of level 9 songs that are easier to clear. Did we mention this is a level 8 Normal chart? Normal charts typically peak at level 7.
- CONTRACT on Normal is rated a 9. For the first 97% of the song, the chart doesn't seem to warrant its level-9 designation, with its eighth-note scales posing next to no threat for players who can clear 8's and 9's, save for a suspicious-looking pattern at measures 48 and 49, roughly 2/3 into the song. But then comes the very last two measures, which suddenly throw sixteenth-note scales and drumrolls combined with scratches. As a fine example of the pass/fail-score dissonance, there are players who have achieved an A or even AA grade on this chart and STILL fail it.
- gigadelic is a pain in the ass no matter what chart you play. Even on Normal, the chart has a few annoying drumroll sections, and an ending with repeated uses of the 7 key and the turntable, and of course a Last Note Difficulty Spike. It's also rated a 9, making it one of the hardest Normal charts in the entire series. Its Hyper chart is rated a 12 simply because of the ridiculous ending, and has killed many potential 8th Dan players, being the final stage of the 8th Dan course in every arcade IIDX version since IIDX RED.
- Most of DJ Mass MAD Izm*'s songs, which are notorious for having extremely high scratch counts, making them extremely difficult to time, especially if mixed in with key notes as well. In SPADA, Shakunetsu Beach Side Bunny's Single Another chart, well-known for a record-breaking scratch count of 667, was introduced into the Kaiden course, to the agony of many top-tier players.
- Most songs ported from Dance Dance Revolution keep the BPM changes, with the stops being a quarter of the BPM instead of stop since IIDX can't handle stops. As such, you have to memorize the BPM shifts all over again. This makes Fascination MAXX an OMES difficult song despite it's low note count and simple patterns, while POSSESSION becomes even more harder to time right than in DDR thanks to weird slowdowns. New Decade IIDX Edition fortunately doesn't feature its signature tempo changes, running at a constant 200 BPM, but that just means you'll be getting genuine difficulty instead of Fake Difficulty.
- A word of advice to those playing on Double: Avoid most Double charts produced before GOLD. Many early Double charts were designed with 2-player non-Battle play in mind, resulting in charts that are extremely awkward to play for one player, including patterns like forcing the player to hit the turntable and multiple keys on both sides, which is humanly impossible. The charts being designed for non-Battle 2P also means that the Light14/DPN and 14Keys/DPH difficulty ratings note will not necessarily reflect their actual difficulty for DP.
- A sterling example of this is Cheer Train (DPA); the song itself is light and cheerful, but the chart is rated a 12 because the chart expects you to be able to frequently hit notes and scratches at once on the same side. Unless you use the Random modifier and are particularly lucky, this chart is humanly Unwinnable by Mistake.
- GOBBLE has a ridiculously difficult DPH chart, with patterns that just don't make sense for a single player. Despite this, it was rated a five on the old rating scalenote . It say something when, upon its arcade debut in copula 14 years later, GOBBLE received a DPA chart with the same number of notes but in far more reasonable arrangements and a lower difficulty rating than the DPH chart. In addition, the song has a non-standard time signature of 4+3/4.
- They Changed It, Now It Sucks: Some complaints came about when SIRIUS introduced Charge Notes and Backspin Scratches, with common concerns being that the game was "turning into" O2Jam (a similar rhythm game notorious for Fake Difficulty-laden charts, with hold notes being a common source of that difficulty), though complaints about these note types have mostly faded since then.
- Uncanny Valley: Kigonshu's video from IIDX Gold may be found to be more than just a little creepy.
- Underused Game Mechanic: In spite of being a "DJ simulation" game, only two out of six types of beatmania cabinets offer headphone jacks: beatmania III and beatmania II (not IIDX, just II), both of which are no longer in production. Given that beatmania IIDX is the More Popular Spin-off and the IIDX cabinet is by far the most common of the beatmania cabinets in circulation, this is rather glaring, given that headphones can be very beneficial to Rhythm Game players in arcades that are noisy (which is to say, almost all of them). Even when Konami designed a new IIDX cabinet to coincide with beatmania IIDX 20 tricoro's release, they still neglected to add any headphone jacks!note
- Viewer Gender Confusion: Rche. Konami knows this and deliberately keeps Rche's gender obscure, going as far as to censor references to it in supplementla material.
- Woolseyism: beatmania USA renamed the flashing "Great" mark to "Perfect", as in Dance Dance Revolution. This makes it stand out better than simply "GREAT" flashing in multiple colors.
