[[caption-width-right:350:The [[NintendoHard over 2000 notes in under 2 minutes]]. That's beatmania IIDX, [[GratuitousEnglish It's too hard!]] [[note]]Specifically 2626. Thankfully, this is just on autoplay mode.[[/note]] ]]
''beatmania'' is a popular RhythmGame developed by {{Konami}} as a part of their {{Bemani}} games. Considered by many to be one of the forerunners of the modern music game. Of course when they realized how popular the arcade version was, Konami would milk the genre for all its worth with spin-offs (involving [[VideoGame/DanceDanceRevolution dance]], [[DrumMania drumming]], [[PopNmusic smacking colored buttons]], and [[VideoGame/{{jubeat}} slapping a grid of buttons]]), and an endless assortment of [[MissionPackSequel Mission Pack Sequels]] and [[ContinuityReboot reboots]].

Originally described as being a "DJ simulator" (which actually ''did'' make sense, given that it had a more hip-hop/house-oriented soundtrack in earlier installments), with what the game has evolved into since the dawn of the 21st century (with almost ''every'' genre of music represented, especially if it's electronic and/or [[ThatOneLevel hardcore]]), its [[NothingIsTheSameAnymore a stark contrast]] to what it used to be.

The basic game is simple, players are armed with a 5-key piano-styled keyboard and turntable, and must press keys or scratch the turntable when notes cascade down the screen corresponding to them. This fills up a Groove Gauge; if the gauge finishes above a certain threshold, you pass, it's just that simple. But, when you look at harder songs though, it's also ''[[NintendoHard anything but]].''

There have been three major incarnations of the game:
* ''beatmania'' (or "5-key" beatmania), the original series. First released in 1997, lasting with new versions until "[[ExactlyWhatItSaysOnTheTin THE FINAL]]" in 2002, where the aging series (it used the ''exact same hardware'', and presumably the same engine, for its entire life) was finally discontinued in favor of...
* ''beatmania IIDX'', first released in 1999 as a spin-off, but becoming the primary series in 2002. Kept the same basic gameplay, but added two additional keys to the control array (for a total of 7), a fancier cabinet (with more lights, more effectors, a widescreen monitor, turntables on opposite ends, an LED marquee, and a bass platform), and a difficulty curve that [[SequelDifficultySpike keeps on getting worse every year.]] What'd you expect when its now on its ''22nd version''?!
* ''beatmania III'', a failed attempt to [[VideoGameRemake remake the 5-key series using more modern hardware]], with higher quality graphics and sound, more effectors, more speakers, effector pedals (which could also be used in special charts), save data on floppy disks, and more. It didn't last long, however, only a few years (it did get its own "THE FINAL" as well).

* ''beatmania IIDX 22 PENDUAL'' (2014 TBA)
[[/folder]]

The series is still popular in Japan, but has seen the shores of the United States a few short times, unfortunately, and shows no signs of another U.S. release.

-----
!!The ''Beatmania'' franchise provides examples of:

* AchievementSystem: Tricoro introduced Tran Medals, rewards you get for doing certain things. While mostly cosmetic, you do need them to unlock some songs.
* AkashicRecords: The "genre" for the song Almagest. It makes some sense, given the the title of the song, but still...
* AmbiguousGender: ''Lincle''[='=]s [[QuirkyMinibossSquad Lincle Kingdom]] brings us Rche, an angel who appears to be female, but sports a male symbol tattoo on their bellybutton. Furthermore, [[AllThereInTheManual supplementary material]] censor out references to Rche's gender.
* AnnouncerChatter:
** In the 5-key series and early IIDX games, a rapper-like voice cheers you on when you insert coins or select a song.
** Starting with ''IIDX RED'', a voice calls out the folder you open during the song select. Later versions let you choose other announcers, often Bemani vocalists like Kanako Hoshino and SUPER STAR MITSURU.
** In ''tricoro'', a robotic female voice can be heard in the card entry, mode select, and result screens, instructing you to insert your e-Amusement pass and select a mode, as well as thanking you for playing at the end of every round.
** ''SPADA'' has a very [[RatedMForManly manly]] LargeHamAnnouncer.
* ArtifactTitle: Inverted for IIDX: the game was originally produced in two different styles of arcade cabinets, the now rare "standard" cabinet, and a "deluxe" cabinet. On the standard cabinet, the game was known as "beatmania II", but the Deluxe cabinets carried the title "beatmania IIDX" on its artwork and software instead. Later on, the standard cabinet was discontinued, leaving only the deluxe one. At this point, "beatmania IIDX" became the official name of the series
** Although, a few errant generic videos (primarily, the [[http://www.youtube.com/watch?v=WG8RK1Zf12s Cyber Beat Nation]] one from 3rd Mix), still contain references to "beatmania II" in them.
* AscendedGlitch: The song "GAMBOL" was notorious for an infamous bug that gave it [[HitboxDissonance unusually small timing windows]]. It was fixed for the arcade version of Happy Sky; the Normal difficulty was the fixed version, and Hyper contained the glitched one. But then, Konami decided to troll players further on RED CS with a new [[http://www.youtube.com/watch?v=giiNrvgclX4 Another]] chart... which makes it even ''worse.''
** Even better, hidden codes on the home versions of DJ Troopers and Empress (spelling out "G-J-H" or "G-J-A" by highlighting songs starting with those letters, and pressing Select on each one) lets the player use those timing windows on ''any'' song.
* AscendedMeme: Some ''Beatmania'' [=DJs=] themselves use the term "Nidera (弐寺)" instead of Two-D-X when talking about the IIDX series, and Ryu☆ described himself in the [[http://www.konami.jp/bemani/popn/music17/mc/song14/handz..html comments]] for ''Second Heaven'' as "That 'Somebody Scream!'guy" as a result of MisheardLyrics.
* AudioAdaptation: The [=ROOTS26S[uite]=] drama [=CDs=] centered around the DJ characters.
* BeachEpisode: ''Resort Anthem'', ironically released shortly before the end of the summer season.
* {{BFS}}: A common element in ''SPADA''[='=]s interface.
* BlindIdiotTranslation: Sometimes happens with the LED marquee. For example, the ''Lincle'' song "Tostugeki! Glass no Kneeso Hime!" is displayed on the marquee as "RUSH! PRINCESS GLASS OVER-KNEE"
* BonusBoss: Beginning on Distorted, versions have featured new extra stage systems integrating with e-Amusement, where meeting certain conditions in-game unlocks additional boss songs in a themed area; usually only accessible on the Extra Stage, and always under themed aliases. Beating all the songs in the area will either lead to the TrueFinalBoss as the One More Extra Stage ... or just lead to yet ''another'' tier of boss songs.
** On Resort Anthem, this changed a bit. There were still bonus bosses, but instead of an Extra Stage system, they were now unlocked with "dellar points" earned in World Tour mode.
** Lincle returns to the previous style with the Lincle Kingdom, the first three bosses involve playing sets with the EX-HARD modifier that are either of the same genre, from the same version, or by the same artist. This time, they were themed around the seven sins.
** Tricoro has Legend Cross, which involves playing sets of songs from a single version to meet a goal that involves the number [[GoroawaseNumber 573]]) to unlock an "Astran light" for that style. Bosses unlock once certain pairs of lights are obtained; each boss so far is a mash-up of other songs from their corresponding mixes (i.e. "SYNC-ANTHEM" is a mash-up of Tatsh songs from RED and Resort Anthem; you need to get both of their lights to unlock it). Clearing one of the bosses nets you a crystal. Get them all and you unlock Thor's Hammer. AAA'ing that song will unlock the [=OMES=] for Tricoro, Plan 8. However, playing Plan 8 removes half of your crystals and relocks Thor's Hammer. After an update in December 2012, players can now buy Devil and Angel Cards with points to unlock the songs for standard play; Angel Cards are more expensive, but allow the song to be unlocked even if it wasn't beaten before.
** And now in Tricoro we have ''another'' bonus boss system, Omega Attack, a.k.a. ''Series/{{Blockbusters}}: IIDX Edition''. Playing the game earns CP, which can be used to buy weapons and upgrades to clear viruses off a map of hexagon tiles. While there are some other new songs and two CS exclusives among them too (i.e. "Tamayura" and "Reflection into the EDEN"), Sector A and Sector B both have one new boss-level song, "トリカゴノ鳳凰" and "Proof of the Existence". Unfortunately, the major flaw is that this system involves lots and lots of LevelGrinding.
* BossInMookClothing: In Resort Anthem, the song "灼熱Beach-Side Bunny" strangely inverts and then subverts this. While it's the One More Extra Stage song, if one listens to it without knowing that, they'd hear... [[http://www.youtube.com/watch?v=attbUNnY5-8 this.]] Not too intimidating, is it? Tell that to the [[http://www.youtube.com/watch?v=HkOG9ARfriM&feature=related 667 scratches.]] Of course, this is a Dj MASS Mad Izm* song, so it [[RunningGag always has a metric ton of scratching]].
** A milder example from the same game: While most Extra Stage songs are fast-pased songs with a sense of "hardcore"-ness, "ANTHEM LANDING", which serves as ''Resort Anthem''[='=]s Extra Stage, is a more modestly-paced and somewhat mellow Latin-esque track.
** Go all the way back to 10th and you'll find the boss song "One More Lovely", it sounds like it came straight out of a DDR game, and even has "HAPPY" as its genre. Yet, it will definitely make an inexperienced player frown, especially at the end (of course)
* BossRush:
** Since the implementation of the extra stage systems (which typically contain the harder bonus songs of a style), there will always end up being an Expert mode course which contains said songs. Class mode also provides the infamous ''Kaiden'' course, which usually consists of the 4 hardest songs available on that particular game; as of Spada, it contains 嘆きの樹 (DistorteD OMES), 灼熱Beach Side Bunny (Resort Anthem OMES), 卑弥呼 (Hidden ultra-difficult song in Empress) and 冥 (Happy Sky OMES, considered the toughest task in all of rhythm gaming).
** ''tricoro''[='=]s Limit Burst song "Sol Cosine Job 2", requires that you do this to unlock it--specifically, play three songs that were One More Extra Stage songs on previous versions
* BossSubtitles: When playing "MENDES" as a OMES, the LED marquee scrolls the message "Warning [=AREA15=] Enemy [[GratuitousEnglish Approrching]]!!"
** "Sense 2007" on Gold did this too, but with the much less frightening "WELCOME TO BLACK ROOM... [[CatchPhrase IT'S PARTY TIME!!]]"
** "Nageki no Ki" scrolled a whole bunch of words relating to grim subjects (DEATH GRIEVES DESTRUCTION MUTATION COLLAPSES SOLITUDE, etc.)
* BossWarningSiren: In ''beatmania IIDX'', after unlocking an Extra Stage boss song, the music select BGM will be overriden by a short loop of the boss, or a new BGM altogether in ''beatmania IIDX 20 tricoro''. In some cases, the background will change accordingly. This only applies to bosses that are made available on the standard music select screen, not bosses accessed through a special "boss select" screen (e.g. ''beatmania IIDX 13 [=DistorteD=]''[='=]s Cardinal Gate or ''beatmania IIDX 16 EMPRESS''[='=]s Empress Place).
* BulletHell: It almost feels like that sometimes ... except you have to ''hit'' all the bullets.
** Parodied in the {{Retraux}} song "Tranoid", whose video involves a fictitious 1980's arcade game consisting of Tran dodging notes from the song's "Normal" chart
* CopyProtection: Unusually for an arcade game, ''tricoro'' has always-on DRM; it must be connected to an e-Amusement network or the game will refuse to start. (note the word "an")
** While unusual by international standards, this type of arrangement (where an arcade game must be connected to its developer's subscription-based online platform, often accompanied by a revenue-sharing and leasing requirement) has been increasingly common in Japan.
* CriticalAnnoyance: A lot of older songs played special animations in the video on missed notes. This happened more in 5-key and early IIDX though, but a few select songs on recent versions have had miss animations (most noticeably Anisakis). Most either contained Engrish ("WRONG PLAY BAD BOYZ KICK YOUR ASS") or otherwise made little sense (what does a [[http://www.youtube.com/watch?v=xdHGDpRnods&feature=relmfu salt shaker]] have to do with a cover of "Brazilian Rhyme"?)
* DarkerAndEdgier: Soundtrack-wise, the entire series has gotten darker and edgier over the years. The first IIDX games were mainly house and R&B-oriented. 3rd to 9th Style brought more electronica, eurobeat, and trance. As SequelEscalation demanded higher difficulty out of songs, hardcore music became a lot more prominent in recent versions. And now look at Tricoro, we got ''dubstep'' now.
** This may be less due to Beatmania itself getting DarkerAndEdgier, and more due to changes in what's popular in the worldwide EDM scene.
** RED and DJ Troopers were also pretty grim, design-wise.
** SPADA speaks for itself.
* DepartmentOfRedundancyDepartment: "Spring Rain (lluvia de primavera)", when translated is "Spring Rain (Spring Rain)"
** Or better yet, SUPER STAR 満-MITSURU- : 満 means Mitsuru.
* TheDevTeamThinksOfEverything: If you use Legacy Note on a chart with no Backspin Scratches or Charge Notes, which Legady Note converts to standard notes, and clear the chart, the game will count your clear as a standard Clear rather than an Assist Clear.
* DifficultySpike: Konami makes sure the songs have more notes at the end before it can be in the game in order to enforce this.
* DistractedByTheSexy: The original music video for "Last Message" in ''7th Style'' has a 3-second cleavage shot, which has caused many players to accidentally slip up at that point. The video was unfortunately removed when it was revived on Gold CS, as Konami was trying to [[ThinkOfTheCensors aim for the Japanese equivalent of an E rating]] (despite the fact that Last Message and its video was on 7th Style's home version already, and it seemed to have no effect on the rating)
** Dai, a male dancer who [[http://www.youtube.com/watch?v=Kwv_vPIL4IQ always]] [[http://www.youtube.com/watch?v=_p_qs3P6nSw appears]] [[http://www.youtube.com/watch?v=gvARFJPd9GA on HHH songs]] (and then switched to [[http://www.youtube.com/watch?v=MIV8HfFDA2U kors k]] on Tricoro) is either overly distracting, or [[WatchItForTheMeme flamboyantly awesome.]]
*** Super Star -Mitsuru- begs to differ in [[http://www.youtube.com/watch?v=uMrmgQ_wDzs ''She Is My Wife'']]. It's impossible to ''not'' be distracted watching kors k, Ryu☆, Yoshitaka, and Sota Fujimori taking part in it.
** The song ''[[http://www.youtube.com/watch?v=EUYiuNrvdWk Tostugeki! Glass no Kneeso Hime!]]'' shows off a princess, in what amounts to a bunch of see through versions of a maid outfit with cat ears. Makes sense, considering the song is about a princess trying to seduce a prince.
* DualityMotif: ''PENDUAL'' alternates between "light" and "dark" phases, each with their own UI tweaks and exclusive songs.
* ExactlyWhatItSaysOnTheTin: The "Gambol Judgement Another" modifier added in DJ Troopers CS. Its effect is self-explanatory if you know the song it's referring to [[note]]"Gambol", by Slake, from the first version - a song notorious for its incredibly strict timing windows[[/note]] and will more likely than [[GameBreakingBug result in you failing any song you attempt it on.]]
* FakeDifficulty: You need your life meter to be at 80% or above at the end of a song to pass. Guess how the people who make the notecharts fake the difficulty...
** Sirius has hold notes and a related note for the turntable where you have to continuously spin it one direction for the duration of the hold note and then snap it back the other way at the very end of the note. Fittingly, TrueFinalBoss "Almagest" used them a lot.
** In ''VideoGame/DanceDanceRevolution'', "New Decade" relies on BPM gimmicks as one source of its difficulty. The song averts this trope in IIDX, where all of its charts are a constant 200 BPM.
** A lot of the high speed boss songs (notably, the MAX series) start on a really low BPM. While this may not sound like much, higher level players who use the high speed mode need to pay attention. Higher level players use something called a "green number", which is how long the note is visible for. Lower BPMs screw this up, but this is made worse with the floating high speed mode where it automatically adjusts the rate to match the green number... and it's not dynamic. Meaning a player who wasn't paying attention is now treated to say Fascination MAX at what would amount to '''8x speed'''
* FanService: Getting good grades on songs will also put different character art backgrounds on the result screen. Some of this may indeed qualify. No wonder the console versions have gallery modes.
* TheFourGods: Cardinal Gate, the [[PerfectRunFinalBoss Extra Stages]] from [=DistorteD=] (IIDX 13).
** To be specific, the names of the four gods are aliases of popular Bemani artists. They are, as follows...
*** Byakko = [[spoiler:Tatsuya Shimizu, AKA Tatsh]]
*** Suzaku = [[spoiler:Yoshitaka Nishimura, AKA DJ YOSHITAKA]]
*** Genbu = [[spoiler:Jun Wakita, AKA wac AKA Shounen Radio]]
*** Seiryu = [[spoiler:Ryutaro Nakahara, AKA Ryu*, who is well known outside of Bemani]]
*** Finally, there's a new 5th god known as Kinjishi, which means a combination of all 4 beasts. [[spoiler:It's Takayuki Ishikawa, aka dj TAKA, one of the most prolific and famous Bemani composers of all time, and the music director for the Beatmania series itself, just as Naoki Maeda is the director for DDR.]]
*** Only Suzaku, Seiryu and Genbu have reappeared in further installments so far.
* GameBreakingBug: 9th Style was the first Bemani game to use PC-based hardware, and it showed. Some songs had timing issues, Gambol was [[RunningGag still broken]], the One More Extra Stage "Quasar" sometimes crashed the machine, and playing "General Relativity" as the first song after a machine is booted triggers a hilarious bug which makes [[http://www.youtube.com/watch?v=xpUX-Dq7K78 getting anything but POOR impossible.]] (Apparently, said song fell back on the timing windows of the previously played song. Since there wasn't a previously played song yet, it choked.)
* GettingCrapPastTheRadar: [=5PM=] [=ETERNAL=]'s [[http://vjarmy.com/wiki/index.php/5PM_ETERNAL#Lyrics lyrics]], my god.
** For Schlagwerk, they [[PrecisionFstrike didn't even have to try.]]
* GimmickLevel: Songs by DJ Mass MAD Izm* are infamous for having extraordinary numbers of scratches; on these songs, how good the turntable is on your controller or arcade machine can mean a whole world of difference. Some non-Izm songs, such as "Checking You Out" and "Plan 8", are also chock full of scratches.
* GratuitousEnglish: Many songs in English have this.
** Stage Clear!! WE EXPECT YOU A NICE PLAY AGAIN
** WRONG PLAY BAD BOYZ KICK YOUR ASS
** Most of the English text in promotional materials or in-game also ends up like this. And don't even ''forget'' about that infamous "GXPERT" typo from RED.
*** They didn't, cause Spada has "[[https://dl.dropboxusercontent.com/u/2351933/1455167_10101978191340554_1401650366_n.jpg BRGINNER]]"
** Songs sung or rapped by Paula Terry, Aaron G, and other such Western vocalists make for SurprisinglyGoodEnglish.
** Anisakis' miss screen reads "He set a foot wrong. However, it nothing but set a foot wrong. You set a foot wrong. It set a foot wrong so like him. The person commits an offense. However, do not set a foot wrong." Whatever that's supposed to mean....
** Dellar points? And what the hell is a "Lincle" anyway? Same for Tricoro, which also has "Astran lights" as part of its BonusBoss system.
*** And we can't forget about Michael [[MisheardLyrics in a boat]], now can we? In reality, he was played by an American, Michael Stillwind (from Konami's Hawaii studio), and voiced by DJ Yoshitaka. Stillwind was notably responsible for his work on the ''VideoGame/DanceDanceRevolution'' Ultramix and Universe games, and for getting [=DM Ashura=] (who won a contest to get onto Universe 2, and then made some later contributions for Universe 3, which later crossed onto X2) a spot on Empress.
* GratuitousGerman:
** "Distress" is [[http://vjarmy.com/wiki/index.php/Distress#Lyrics sung in German]]. It helps that the remixing artist, [=TaQ=], was born in Germany.
** The [[http://p.eagate.573.jp/game/2dx/19/p/newsong/s_todestrieb.html music production info for "Todestrieb"]] is written in German rather than Japanese.
* GratuitousItalian: "Spada" is Italian for "sword", fittingly enough.
* HarderThanHard:
** Black Anothers. Dear God. The song [[http://www.youtube.com/watch?v=qqkWIWbO14c&fmt=18 MENDES]] (pictured in the lead) ''completely'' redefines NintendoHard (with 2,626 notes. The average boss has 1800-2000).
*** Black Anothers are slightly OlderThanTheyThink. The final two stages in Gold CS's Kaiden course, Vanessa and Kamaitachi, have special charts then exclusive to that course. When/If you get to these stages, you'll notice that where the difficulty should be shown, there is ''[[NothingIsScarier blank space]]''. Later console installments give them proper Black Another designations.
*** [[http://www.youtube.com/watch?v=HbZqezK48ro&feature=related Here's a video of Mendes played on piano]].
** Oh and then there's the [[http://www.youtube.com/watch?v=xR7jIk3wZ84 Doubles Black Another version]] at 2603 notes.
** Mendes Black Another has been FC'd on a Dual Shock controller ... [[http://www.youtube.com/watch?v=lMUspR3mKtA&feature=related on half speed in training mode]]
** Empress adds "Hazard"; One combo break and you're ''toast''. On the plus side, you still get to play all the stages on your credit even if you do fail.
** Lincle added a new modifier, EX-HARD. This modifier increases the damage taken by the lifebar on misses to 18% at once. But just like the original HARD modifier, it removes the 80% passing requirement, but makes you fail the stage if it hits zero. If this isn't literally Harder than Hard, we don't know what is.
** Tricoro revives the "LOW-SPEED" modifier dropped after 6th CS, by adding the ability to set HI-SPEED ''below'' 1.0x . Suddenly 灼熱Beach-Side Bunny on half-speed looks ''[[http://www.youtube.com/watch?v=kOOYhd7RkFU a lot worse.]]''
** SPADA introduces the "†LEGGENDARIA" difficulty for the Spada†leggendaria series of boss songs, available in their own folder and only if you are using PASELI[[note]]Konami's digital arcade currency[[/note]] rather than coins to play the game. While nowhere near the Black Another series, these charts are still not for the faint of heart.
* IdiosyncraticDifficultyLevels: Formally Light 7, 7 Keys, and Another. Happy Sky adjusted the ranking scale and re-named the first two to Normal and Hyper.
** When it was first introduced, Another was actually [[ExactlyWhatItSaysOnTheTin another arrangement]] for the song, typically harder and more complex. Now? Nine times out of ten, it's just a harder chart.
* HighDefinition: Although the arcade ''IIDX'' series uses widescreen monitors, only in ''tricoro'' did the series actually support proper 720p HD. In fact, games up to ''tricoro'' ran in 640x480--that means technically, the graphical assets you see on screen are actually stretched!
* KyuAndDanRanks: Dan'inintei mode, a.k.a. Class Mode
* LastNoteNightmare: Due to the 80% lifebar requirement for passing, a song with a ridiculous ending is practically a series trope on its own.
** Although, [[AccidentalInnuendo it can be easier with HARD on]].[[note]]The HARD modifier swaps out the 80% life bar for a traditional lifebar where you only fail if you hit 0%. Thus, HARD actually makes songs with hard endings easier to clear as long as you can stay alive.[[/note]]
* LevelGrinding: One of ''Lincle''[='=]s unlock methods. ''tricoro''[='=]s Omega Attack event, a post-game board game, takes this to WTF levels; completing the first sector takes at least ''forty'' playthroughs. The less said about the second sector, the better.
* LoadsAndLoadsOfCharacters: Some videos outright show this.
* LostForever: ''tricoro''[='=]s color events have several songs crossovered from console IIDX games, all of which were originally gone permanently if you failed to unlock them during their respective events. This was changed in an update (on August 14, 2013, over 8 months after the first event ended) which allowed players to buy the unlocks using Dellar points, at 5K for Normal, 10K for Hyper, and 15K for Another. It requires tons of LevelGrinding, but they can once again be unlocked if you missed them the first time.
* LuckBasedMission: The Random modifier, which rearranges notes on a per-column basis. A good random order can make a chart easier, but sometimes it will just make the chart more difficult. Those trying to get better will use Random in order to learn awkward and difficult patterns.
* MarathonLevel: Scripted Connection⇒ & Shade, both lasting about 6 minutes long. Both by the same artist to boot. You see, the part of the song you actually play is dependent on the difficulty, and the soundtracks have the full version as all three versions strung together. However, on the console version of Happy Sky (and beginning on Gold AC), all three versions of Scripted Connection have full sets of charts (the N-mix, H-mix, and A-mix respectively). The "long mix" of Scripted Connection is also a hidden track on Happy Sky CS, where it clocks in as the longest single song in the entire series.
** Resort Anthem's extra stage, ANTHEM LANDING, also counts as this despite having no long version to play.
** Tricoro has 仮想空間の旅人たち (Kasoukuukan no tabibitotachi) which does the same thing, except between the single and double versions.
* MercyMode:
** If you are using a Groove Gauge in whch a 0% is instant failure, any damage you take while your Groove Gauge is 30% or less will be halved.
** In ''tricoro'', the requirements to unlock a LIMIT BURST song, other than playing a 3-stage set of songs from that song's game and qualifying for extra stage[[note]]on your last stage, all-Great combo a level 5 chart or lower, Full Combo a 6, finish a 7 with 100% gauge, or simply clear an 8 or higher[[/note]], are initially extremely harsh, but relax every week:
*** Phase 1: You need your first three stages' difficulties to add up to 33[[note]]To put it in perspective, this means the average difficulty of your songs must be 11 or higher[[/note]] AND you need a Full Combo! And even then, only the Another chart will be available.
*** Phase 2: You now only need to clear the three stages with an EX-Hard gauge. In addition, the Hyper chart becomes available, and requires a total difficulty of 27[[note]]average difficulty 9 or higher[[/note]] and a Hard gauge.
*** Phase 3: Another only requires a Hard clear, Hyper only requires a standard clear. Normal finally becomes available; you need a total difficulty of at least 18[[note]]average difficulty 6 or higher[[/note]], and it will unlock as long as you clear your songs at all (even Assist Clear).
*** Phase 4: Just clear all three stages (again, Assist Clear is OK).
** If you fail a chart that is less than level 6 for your first stage, you'll still be allowed to advance to the next.
** If you are playing on a machine that is connected to the official e-Amusement network, you can use PASELI (proprietary e-Amusement currency that you purchase with real money) to purchase a DJ Vip Pass, which is a pay-to-use Mercy Mode: you'll be guaranteed three stages even if you fail your first two.
* MinigameCredits: [=DistorteD=]'s credits roll lets the player spin around the camera angle on the monotonous 3D backdrop soaring through the background with the turntable, it's not a "game" per say but still.
** [=SIRIUS=]'s credits roll has a spinning disc in the background that can be manipulated with the turntables.
** Subverted by Empress, while the credits are not a minigame, the ending theme itself became a playable track ("THANK YOU FOR PLAYING") as part of the final set of timed unlocks, with the credits roll as its background video. Ironically, the song has been revived past Empress, and it ''still'' has Empress's credit roll attached to it. The ending for Resort Anthem, "Everlasting Resort", also does the same thing. Will someone ever notice and switch it out with a generic video? At the rate we're going, no.
** The subversion is averted for "Vermillion" (Sirius ending theme, debuting on Resort Anthem) and "The Last Striker" (DJ Troopers ending theme, debuting on the PlayStation 2 version), which got their own dedicated videos when they became playable tracks. In the latter case, its a ClipShow of generic videos.
* MissionPackSequel ''IIDX'' has about 19 installments to its name, each with different art/song themes. Not exactly CapcomSequelStagnation though, since every mix has new songs, new features, and often remove or bring back older songs,
* MythologyGag: The ''entire'' video for [[http://youtu.be/g3dvBL3wegM Illegal Function Call on Tricoro]] is a tribute to the original 5-key series in abstract CGI sequences.
** Capacity Gate's unlockable menu music on Resort Anthem is a remix of the ''VideoGame/DanceDanceRevolution Extreme'' menu music.
* NintendoHard: ''IIDX'' is regarded by many RhythmGame conoisseurs as one of the most hardcore rhythm games in existence, if not ''the'' most hardcore.
** The groove meter 80% passing grade for all songs greatly contributes to this.
** Unlike the other Bemani games, beatmania's timing is actually based on the amount of frames the button was pressed before or after the note passes the marker. By default, the Just Great timing happens on the frame or the one before, meaning a player has about a 16ms window of time to hit a note "perfectly".
*** And to make things worse, the game's timing ''heavily'' depends on the monitor being as close to 59.95Hz as possible. Did the monitor decide to be just 0.05Hz off? I hope you enjoy scoring terribly.
*** The aforementioned GAMBOL glitch? That's what happened when the "Great" and "Just Great" timings basically merged and shrunk to "you have to be on the exact frame to count".
* NoFairCheating: Scores achieved with the "Auto-Scratch" modifier don't get saved. In ''IIDX'', this applies to the "5 keys" modifier as well. With the introduction of continuous notes in IIDX 17, the Legacy Note modifier which removes these has the same effect. Currently, scores with such "Assist" mods will save, but will be marked with "Assist Clear" status. This is because while Assist mods will make songs easier to clear, they provide no benefit to your score as they deduct playable notes.
** This backfires on people who use the 5key modifier on classic beatmania songs. Using the modifier on them will load up the old 5key chart from beatmaina, but will still count it as an Assist Clear.
* NoPronunciationGuide: The song "AA." WordOfGod has confirmed that ''there is no official pronunciation.'' To further compound the confusion, the song is sorted at the beginning of the alphabet in ''IIDX'' and ''DDR'', but its remix in ''Sound Voltex'', "AA [=BlackY=] mix", is sorted under ダ, presumably for its FanNickname ダブルエース ("Double-Ace").
* OminousLatinChanting: Xepher, and perhaps ''any'' Zektbach song actually.
* OneHitPointWonder: Hazard Mode in Empress. Any negative note judgments other than excess-key-induced [=POORs=] will result in a GameOver.
* PerfectRunFinalBoss: One More Extra Stages.
* PublicDomainSoundtrack: Not rampant, but many classics in the series ("V" and "Kakumei" especially) are indeed remixes of other classical pieces ("The Four Seasons: Winter" and the "Revolutionary Etude", respectively)
* RageQuit: Seeing "78%" (2% lower than the required gauge to pass the song) tends to cause this.
** And then there's [[http://www.youtube.com/watch?v=mX1Lnl5ihXY this one guy]]. Skip (or watch all the way) to around 2:06.
* RapidFireTyping: [[PlayingWithATrope Played with]] MoreDakka in the SPADA song ''miracle 5ympho X'' on Another. There's a section halfway in the song that drops a rapid fire bassline, complete with a visual on the BG movie of a girl shooting a machine gun. Some FridgeBrilliance come into play when you realize that you're hitting the keys at the average rounds-per-minute of a machine gun, as the song is 210 BPM and section is nothing but 1/16th notes.
* RankInflation: Grades go from F to AAA. Similarly, in Class mode, you have the 7th through 1st ''kyu'' grades, then 1st through 10th ''dan'', and finally, ''kaiden''.
* RecurringBoss: While dan course songs tend to scramble around with each new version, "THE SAFARI" in particular is notorious for consistently being the last stage of single-player 7th Dan, a position it's had since the introduction of the kyu/dan system on ''7th Style'' in 2002. "gigadelic" is also notorious for this in 8th Dan, where it's been the final stage in every version since the song was introduced in ''IIDX 11: RED'', with the sole exception of ''IIDX 15: DJ Troopers''.
* RecurringRiff: Every Suzaku song has a distorted guitar screech in it, appropriately dubbed by many fans as the ''Suzaku Scream''.
* RecycledSoundtrack: Songs will often be continually "revived" (remaining alongside new songs on a newer version of the game, or appearing alongside older songs on console versions) quite a few versions, especially if they're fan favorites.
** "V" is notorious for this. It debuted on 5th Style, and got revived on almost ''every'' console version after that until IIDX 1). Fans suspected Konami of "ruining the joke" that [[YouPutTheXInXY "you can't spell 'revival' without 'V'"]].
** Then, Empress brought us "V2" ... which was nothing more than a cut of an extended version of V from dj TAKA's album "milestone".
* RedZoneRemixVid: Trope creator.
* RequiredSpinoffCrossover: Throughout practically every Bemani game actually, songs will often cross over from Beatmania to other games, or vice versa. Special mention goes to Kakumei, a collaboration between dj TAKA and Naoki (who were both the producers for their respective franchises at the time), which appeared as the One More Extra Stage on both IIDX 7th Style and [[VideoGame/DanceDanceRevolution DDRMAX2]], both of which were the 7th main release in their respective series. At the same time, a version of "MAX 300" (which was the Extra Stage song on [=DDRMAX=], a first for the series) was also the main Extra Stage on 7th Style, it too being the first Extra Stage in the series.
** A few other DDR boss songs have appeared since, including Sakura (Extreme extra stage, 8th Style extra stage), Paranoia Survivor Max (Extreme extra stage, 9th Style unlock), Fascination Maxx ([=SuperNOVA=] extra stage, as Gold OMES), Pluto ([=SuperNOVA 2=] extra stage, unlock on DJ Troopers CS), and Saber Wing (DDR X extra stage, beat unlock on Resort Anthem). While not a boss song, Sakura Storm (DDR Universe 3 and X2) also came up as an unlock on Resort Anthem.
** The "Nadeshiko Rock" song from [[PopNMusic Pop'n]] practically crossed over to ''every'' active Bemani franchise, IIDX included, around Empress.
*** And then there's DJ Yoshitaka's "FLOWER", which does the same, though it had to be retooled into a rock arrange for ''Guitar Freaks & Drummania''.
** Then came the [=LincleLink=] and events for Resort Anthem and Lincle, whose point was to allow players to unlock songs from the latest Jubeat versions on IIDX and vice-versa by playing certain combinations of songs on both. Lincle also brought the "Append Travel" event, which brought more promotional Jubeat crossovers to other Bemani titles as well.
** Tricoro's other Limit Burst songs[[note]]There is no "default" Extra/One More Extra Stage-only song like on previous versions, but there are still conditional unlocks only available on the extra stage labelled on the results screen as "LIMIT BURST" songs.[[/note]] have all been boss songs from other Bemani franchises. So far, these have included a new mix of "New Decade" from ''VideoGame/DanceDanceRevolution X2'', "neu" (ThatOneBoss from ''[[PopnMusic Pop'n Music Adventure]]''), "Hollywood Galaxy" from ''VideoGame/ReflecBeat'', "DAY DREAM" from [=DrumMania and GuitarFreaks=], and "Timepiece Phase II', also from GF&DM.
* {{Retraux}}: The Parallel Rotation extra stage system in ''SIRIUS'', which echoes 5 of the previous 6 styles.
* RuleOfFun: It's not really DJ simulation anymore. But does that really matter?
* RobotDog: The mascot for ''SIRIUS'' is one.
* {{Roguelike}}: The "Qprogue" event in ''SPADA''. After each play session, you play a minigame where you guide your Q-pro through maps to fight monsters and unlock new charts.
* SelfImposedChallenge: HARD mode, and the Gambol judgement modifiers
** Then there's also a mode called WINDOW HOLD, which keeps the in-song HI-SPEED and SUDDEN+ controls active after hitting Start (instead of requiring you to hold it down). The joke of this is that because the keys and turntable respectively are used to configure those settings, you're supposed to play the song with them ''constantly changing on every note!'' [[http://www.youtube.com/watch?v=6OL2z8y51Vw See?]]
* SequelEscalation: The difficulty scale originally went from 1 to 7. Then came the 7+, which were later relabeled as 8. Then there were 8+s. Then Version 12 bumped it up to be out of ''12.''
** But, TheComputerIsALyingBastard. Before Happy Sky introduced 9-12, the 7Keys/Hyper difficulty rating would be exactly the same as the Another difficulty rating. This caused hard songs to be mislabeled. One of the most {{egregious}} examples is "Mr. T (Take me higher)", rated a 10 on Another after Happy Sky, to be labeled as a ''4''. Even worse than that is "5.1.1.", which up to Happy Sky was rated a 1 on Normal and Hyper, but has a [[SurpriseDifficulty pretty]] [[ThatOneBoss brutal]] Another chart.
* SeriesMascot: Tran, the [[HumanoidAliens Humanoid Alien]], he appears in several background videos. But, this hasn't stopped the individual versions from having their own mascots.
** There's also the various (mostly female) [=DJs=] that go on the promotional art.
* SevenDeadlySins: Lincle introduces a series of bosses named after the seven sins.
** {{Greed}}: Mamonis, a man apparently made of shadows who attacks using money. AKA [[spoiler:kors k]]
** {{Lust}}: Ashemu, a [[HornyDevils succubus]] with knives. AKA [[spoiler:Asaki]]
** {{Sloth}}: Bulluvegola, a set of stained-glass circles. AKA [[spoiler:96]]
** [[VillainousGlutton Gluttony]]: Beridzebeth, some sort of pink mech with wings and a scythe. AKA [[spoiler: PRASTIK DANCEFLOOR]]
** {{Pride}}: Rche, an [[spoiler:trap]] angel with four black wings. AKA [[spoiler: Tomosuke]]
** {{Envy}}: Levaslater, a mech that resembles a blue dragon. AKA [[spoiler: Ryu & Starving Trancer]]
** {{Wrath}}: STN... another mech soldier [[spoiler: whose armor falls off in another boss song to reveal the true demon]]. AKA [[spoiler: Tatsh]]\\
\\
Additionally, there are two more songs that aren't any 7 sins, but related to them;
** Apocalypse: Neulakyussra, a four-armed, three-headed being [[spoiler:and the true form of STN]], infused with the power of the seven sins. AKA [[spoiler:L.E.D.-G]]
** Rebirth: [[SpellMyNameWithAnS Cuvelia/Cybele]], yet another mech (angel motif). [[spoiler:If you're doing good enough in the song, the armor will break to reveal a blue-haired girl with laser-swords floating around her.]] AKA [[spoiler:Taka]]
* {{Shiritori}}: Speaking of the Lincle bosses, STN's song is unlocked using alphabet-variation shiritori, where you progress by playing sets of songs that link together, including the last and first songs.
* ShoutOut: A song in ''Tricoro'' named [[http://www.youtube.com/watch?v=2o9TlCFApOQ Illegal Function Call]] makes innumerable shout outs to the 5-keys era in its music video.
* SoundtrackDissonance: "Sasoribi"/"Scorpion Fire"/"Anti-Ares", "Ganymede" and "Bag" to name a few (the latter debuting in VideoGame/DanceDanceRevolution first).
* SpellMyNameWithAnS: A number of songs have multiple ways to read their names; "Shonen A"/"Kid A" ([[{{Radiohead}} not that one]]), and "Gattai Sayo! Strong Jaeger!"/"The Strong Jaeger," just to name a few. This is primaraly a result of the cabinet's LED marquee: since it can only display English characters, songs with foreign titles will either be romanized, translated, or show something completely different on the marquee.
* StandardSnippet[=/=]{{Sampling}}: A sampling-related conspiracy theory occurred in two particular styles: a stock sample of someone yelling "SOMEBODY SCREAM!" appeared in two different songs on Gold (Second Heaven and FIRE FIRE, but more infamously in the former), followed by a sample of someone saying "1-2-3-4-5-6 do it!" appearing on ''three'' different songs on DJ Troopers ("Be OK", "Icarus", and the aptly titled "Do it!! Do it!!", which consisted almost ''entirely'' of that sample.) Even more ironic was the fact that the last of those two were both [[BonusBoss Military Splash songs.]]
** SampledUp: (InUniverse) kors k's boss song on Lincle (fittingly, the one [[JustifiedTrope representing the sin of Greed]]) is pretty much a whole bunch of [=StripE=] and disconation songs thrown into a blender. No wonder its titled "[[MeaningfulName THE SAMPLING PARADISE]]"
** "Schlagwerk" takes a couple lines from ''BadBoys'': "Oh, this is bad." and "This is [[PrecisionFStrike fucked]] up!"
* StatMeters: RED added a new stat display (typically shown on the other player's unused play field), which shows a series of bars comparing the player's current score to that of an optional rival or the high score.
* StellarName: [[http://vjarmy.com/wiki/index.php/Jun_Wakita Jun Wakita's]] trademark. Among others, "Regulus", "Spica" and "Scorpion Fire" are all named after stars (SF is an allusion to Alpha Scorpii/Antares), "moon_child" and "Ganymede" refer to moons, and "Waltz of the Big Dogs" (the sequel to "Scorpion Fire") refers to the Canis Major constellation.
** The game "Waltz" debuted in, SIRIUS, also qualifies and also refers to the same constellation.
** Taken UpToEleven with the song "To My Star" from Tricoro. The title has a star (obviously), it's a star-type song (the genre is STARPOP), it's sung by a star (Kanako ''Hoshi''no), it's about becoming a star (specifically, a pop singer), it has a cameo from a star (SUPER STAR 満-MITSURU-)...
* TagLine: Most games in the series have one, ranging from the simple ("It's party time!" from ''GOLD'') to the [[{{Engrish}} nonsensical]] ("Next Link Various Tunes Change the World [ TRI ] For The Future !!!" from ''tricoro'').
* TakeThat: When Ryutaro Nakahara stopped using an asterisk and started to use a star for his Ryu☆ alias, his brother kept asking his "What's with that?" The song Be Quiet is his answer.
* TheArtifact: Remember back in the day? When this game actually ''did'' primarily have hip-hop, and as such an actual justification for having scratching in its controls? Yet, it remains, even though most of the songs are now either hardcore electronica or pop. The IIDX series ''did'' start with mostly J-pop and R&B, but then began to diversify, to the point where on most songs, the turntable is just another trigger for sounds that aren't scratching.
** That hasn't stopped songs with legitimate scratching from showing up in the modern era though. Just beware if you encounter a song by recurring regular "Dj MASS Mad Izm*"
* ThemeNaming: Since the 11th main installment of the ''IIDX'' series, every installment has had some sort of color theme to it, with a subtitle relating to the colors, such as "RED" ([[FunWithAcronyms Revolutionary Energetic Diversification]], primarily all dark red/black), "Happy Sky," (skies and clouds) "Gold," (black and gold with a premium nightclub motif), "DJ Troopers" (military and camouflage), "Empress" (pink and black with jewel motifs), "Sirius" (metallic silver and blue space-age), "Resort Anthem" (a BeachEpisode), "Lincle" (blue, orange, and white with some atom trails), "Tricoro" (mostly greyscale with red/blue/yellow accents, and lots of abstract 3D stuff), and now "Spada" (dark brown/silver/red, medieval. Even the grade letter graphics, which have barely changed since 9th Style, got changed from their traditional techno look to a more medieval font)
** Also, the Extra Stage songs often have some kind of theme to them. See TheFourGods above. IIDX 16: Empress also has a set of regular One More Extra Stage songs with a sweets theme and an alternative Extra Stage called EMPRESS PLACE that centered around former "empresses" like Cleopatra and Marie Antionette.
** Similarly, in ''15th Style: DJ TROOPERS'', there is a new version of Cardinal Gate called ''Military Splash'' that has 4 Bemani artists hiding their identities behind battle formation aliases.
*** Lion = [[spoiler:dj TAKA]]
*** Scorpion = [[spoiler:Toshiyuki Kakuta, aka L.E.D.]]
*** Kraken = [[spoiler:Ryu*]]
*** Eagle = [[spoiler:Kosuke Saito, aka kors k, who is also a known artist outside of Bemani]]
*** Humanoid = [[spoiler:DJ Yoshitaka]]
** In Sirius, the extra stage system was a series of [[NostalgiaLevel Nostalgia Levels]] based off versions 11 through 15. Each tier had two previously console exclusive tracks, a new remix of a song from that version, and a new song performed under an alias used by a boss song on that version. When played, the songs even used the matching interface skins from their respective versions.
** On Lincle, the extra stage system returned to a more Cardinal Gate-esque system called "Lincle Kingdom", which was themed around the Seven Sins.
** The Spada†leggendaria songs have the artists named after [[PublicDomainArtifact famous]] [[ArmsAndArmorThemeNaming swords]]. Before that there were some sword named songs in the series (Claiohm Solais and Ascalon). Another difference is that the artists so far are ether commission artists or recent additions to Bemani (and that most them have songs in VideoGame/SoundVoltex]]). The artists are:
*** Ama-no-Murakumo-no-Tsurugi [[spoiler: AKA [=REDALiCE=]]],the weapon of [[JapaneseMythology Susano-o]]
*** Gram [[spoiler: AKA DJ Genki]], referring to [[NorseMythology Sigmund's sword]]
*** Durandal [[spoiler: AKA DJ Noriken]], the blade of [[Literature/TheSongOfRoland Roland]]
*** Caldabo[[{{Engrish}} r]]g [[spoiler: AKA USAO]], a misspelling of Caldabolg, a weapon from IrishMythology
*** Falsion [[spoiler: AKA DJ Shimamura]], A corruption of the word Falchion, an European weapon. It could be a MythologyGag to a Konami shooter called "FALSION" or a ShoutOut to VideoGame/FireEmblem
*** KUMOKIRI [[spoiler: AKA OSTER project of "Levan Polka" fame.]], Kumokiri is a sword from a Japanese epic poem in which it was used during the Genpei War
* TitleDrop: "[[TitleScream IIDX GOOOOOOOOOOOOOOOOOOOOOLD!]]" The full version of the opening theme, "GOLD RUSH", also proceeds to name off ''every single IIDX game up to that point'' during the breakdown.
** The song's follow-up, "[=B4U (BEMANI FOR YOU MIX)=]", does something similar. While the original already contained a DDR title drop, this one also rapidly names off other Bemani franchises.
* UniversalAdaptorCast: For example, [[http://vjarmy.com/wiki/index.php/Ereki Ereki]], WhiteHairBlackHeart has a villain-like demeanor in [[http://www.youtube.com/watch?v=-vmzwfI52Ww TERRA'S videos]], but is simply a [[CameraFiend stalking photographer]] in songs like [[http://www.youtube.com/watch?v=zzN-nqXJTS8 Love-Shine]]. This is just one example of very surprising dissonances with personalities in different videos.
** Interestingly meta in the series' "canon" because every character has externally-established (typically through art books) backgrounds and in actuality are simply ''people who play IIDX.''
* VariableMix
** ''Tricoro'' does this for the game's [[http://www.youtube.com/watch?v=8ajvwUdMvcs menu themes]] now (they used to cut in after a loading screen).
* XtremeKoolLetterz: Miracle 5ympho X
