History YMMV / DJMAX

** In ''Portable 3'', they ported "NB Rangers Nonstop Remix" from ''Technika 2''. Much excitement from fans until they realized after finally playing it that the entire second half containing "NB Power" and "Dark Envy" was removed, leaving only "NB Rangers" and "NB Rangers: Returns". Cue the very disappointed fanbase expecting all four songs.

** ''Black Square'', ''Trilogy'', and ''Fever'' receive criticism for their Key Assist feature, in which hitting a note with the correct timing but the wrong key still count as a hit, effectively defeating the point of hitting the point of having note lanes triggered by hitting specific buttons. While there is a 20% reduction in score for hitting the wrong key, it doesn't incur any combo- or Rate-related penalties, thus watering down the value and satisfaction of Max Combos and high-accuracy plays (including 100%) for many players. Perhaps in response to this, ''Trilogy'' later received a patch to disable Key Assist, and all subsequent ''DJMAX'' games remove this feature.

* SugarWiki/HeartwarmingMoments: An [[https://www.youtube.com/watch?v=w4KmruCH9HE interview]] with Paul Bazooka revealed that the ''DJMAX Respect'' song "Don't Die" was composed and titled in dedication to a long-time fan of his who fell into despair over failing school and hoped that his new single would take this fan, and others like him, out of that despair.

* SugarWiki/MostWonderfulSound: "Max Combo! What a crazy mix!" ''Respect'' replaces this with an equally wonderful whoosh when you get one, and ''SUPERBEAT [=XONiC's=]'' equivalent: "All Combo, awesome!"

* ThatOneBoss: Many of the recently-released ''Technika'' charts. Charts like [[https://www.youtube.com/watch?v=jN3qQcmKI1k "End of the Moonlight" TP]] and [[https://www.youtube.com/watch?v=Zdc4e1_u3Bo "Thor" TP]] will make your fingers hurt like hell.

* ThatOneLevel: ''Black Square'' 's Club Tour Missions. In addition to requiring you to complete a song with certain, often-strict requirements (such as passing a song with more than ''x'' percentage or getting ''y'' combo), every time you restart or fail, you have to pay in-game currency to retry!

** The Remix Mode in ''Respect''[='=]s ''Portable 3'' DLC pack is exclusive to the pack's missions, much like other DLC packs with gameplay changes as its main gimmick. Also, the mission set only has "Workstation Set" difficulty songs, ''Portable 3''[='=]s equivalent to Maximum difficulty, with the other two difficulty levels being nowhere in sight. If you didn't already spend a lot of time playing WS difficulty songs back then in the original game, you'll probably be spending a lot of time holed up in practice mode.

** "Low Score" is another popular ''Technika'' challenge, where the players are aiming to score as low as possible without failing the song. The challenge here is to balance where to miss notes, play them off-beat (which can screw with players' heads due to being keysounded), and which notes to hit accurately to sustain themselves.

* DefaultSettingSyndrome: Due to ''Respect'' not having a penalty on Fever charge rate when using Auto Fever (the default Fever option) as well as removing the speed increase when reaching certain Fever thresholds, most players just stick to it because it elmininates the issue of having to press the button manually.
%% * 5 Key in ''Online'', 4 Buttons in ''Portable''

** Perhaps one of the biggest issues with Freestyle Mode's combo-based unlocks is that once you commit to a combo target, you can't really do anything else in Freestyle until you reach your goal (or miss a note, wiping out the ''entire'' combo). As of ''Respect'', you have the option to disable Freestyle combo with a setting; doing so not only prevents combos from carrying over from one song to the next, but if you have an active Freestyle combo, it will be frozen and protected until you turn the option back on.

* AuthorsSavingThrow: [[WordOfGod According to Respect's lead producer Bexter]], the North American release of ''Respect'' was supposed to have a DLC schedule where one pack gets released every three months, like the Korean version. They eventually decided upon releasing the four DLC packs available at the time [[https://www.youtube.com/watch?v=vqQUuQEWRTM all at once]] a few weeks after the game's launch, and the simultaneous global release of the ''Black Square'' DLC shows that Rocky Studio is keen on keeping overseas versions' DLC schedules on par with Korea's.

** Like in ''VideoGame/{{O2Jam}} PC'' and ''VideoGame/TheIdolmasterCinderellaGirls'', “hold” notes don’t just have to be pressed with perfect timing, they also have to be ''released'' with perfect timing. Otherwise it will be counted as "MAX 90%" or below, which annoys some players who aren't used to this mechanism and want to get a perfect score on some songs.

** ''Respect'' added an update that introduces timing window adjustments and an indicator of whether you hit a note too early or too late...which were then removed in a July 2020 patch, and were not included in ''Respect V''. It's been speculated that Konami (of ''VideoGame/{{beatmania}}'' fame) holds patents of some sort on those features, but no official explanation has been made by the publisher other than that there were "unavoidable circumstances".

* PortingDisaster: While ''SUPERBEAT [=XONiC=]'' on Switch isn't a problem at the software level, it suffers because the Switch's buttons and analog sticks are not horizontally symmetrical; specifically, the left stick is ''above'' the directional buttons and the right stick is ''below'' the ABXY diamond. Cue missing analog notes all over the place, even if you ''haven't'' [[DamnYouMuscleMemory played the versions of the game on Sony platforms]] (which do have vertically-aligned sticks). You can try to use the touchscreen instead, but the game is unusually harsh when it comes to scratch notes, which seem to have a tendency to drop if you're so much as a few pixels off.

* NightmareFuel: The [[https://www.youtube.com/watch?v=xD2W49jPKF4 NB Girls]]. For those who are currently in relationships, engaged, or married: imagine them pulling their tricks on you and your significant other. ''Especially'' if you've been together for a long time. At least the NB Rangers make it obvious that they're the ones being assholes, even if their methods involve violence.

** Lke in ''VideoGame/{{O2Jam}} PC'' and ''VideoGame/TheIdolmasterCinderellaGirls'', “hold” notes don’t just have to be pressed with perfect timing, they also have to be ''released'' with perfect timing. Otherwise it will be counted as "MAX 90%" or below, which annoys some players who aren't used to this mechanism and want to get a perfect score on some songs.

** Similar case with ''VideoGame/{{O2Jam}} PC'' and ''VideoGame/TheIdolmasterCinderellaGirls'', “hold” notes don’t just have to be pressed with perfect timing, they also ''have'' to be released with perfect timing. Otherwise it will be counted as "MAX 90%" or below, which annoys some players who don’t get used to this mechanism and want to all-perfect some songs.

* StopHavingFunGuys -- You're not allowed to play the ''Portable'' games or ''Trilogy'' but not use Fever.
** Still present in ''Respect'', but ironically now applies to people who ''do'' use Fever online. Since scoring is mostly accuracy-based in that game, a lot of online players would much rather have Fever disabled.

** Similar case with ''VideoGame/{{O2Jam}} PC'' and ''VideoGame/TheIdolmasterCinderellaGirls'', “hold” notes don’t just have to be pressed with perfect timing, they also ''have'' to be released with perfect timing.

** The ''VideoGame/{{Deemo}}'' DLC pack in ''Respect'' has been criticized by players for not having [[MusicalGameplay keysounds]] unlike the rest of the game. Such an issue was [[OlderThanTheyThink already present before]] with the free DLC songs "Always" and "Tok! Tok! Tok!", but the practice only got criticized with the ''Deemo'' pack's release as it had a price tag attached to it.

* SuspiciouslySimilarSong: [[https://www.youtube.com/watch?v=EmhufQl5ieI "Cypher Gate"]] has a lot of similarities with [[https://www.youtube.com/watch?v=x_7pPTEGsig "SOLID STATE SQUAD"]] from ''VideoGame/{{beatmania}}'', earning the former the FanNickname of "Korean Solid State Squad".
