* CrowningMomentOfFunny: [[http://www.youtube.com/watch?v=QixDSEoxig0 800$ BOOM]]
* DamageSpongeBoss: Hardcore of the North Single Expert has over 800 steps. By no means easy, but the arrangement and consistency makes it easier than some charts that have fewer steps.
* FanonDisContinuity: Every fanmade "game" =/= In The Groove.
* ItsEasySoItSucks: Every song under 10 blocks seems to suffer from this by the fanbase, despite a great deal of them actually being loads of fun.)
** Thus this leads to more and more expert only Nintendo Hard custom songs and packs.
* ItsHardSoItSucks: On the other hand, ITG's catering to the top-scoring crowd and abundance of NintendoHard charts, coupled with a large majority of ITG discussion being amongst higher-end players, means beginner players easily get intimidated from playing.
* GoodBadBugs: In the r21 patch for [=ITG2=], players can play custom stepfiles, but the song cannot be tagged as being longer than 2 minutes. Emphasis on "tagged"; [[LoopholeAbuse the implementation of the feature read from the music file's metadata to determine length.]] In the updated r23 patch, songs now automatically cut off at 2 minutes and 15 seconds, regardless.
* [[AmericansHateTingle Japanese Players Hate ITG]]: You would expect that since it's the SpiritualLicensee to DDR and with much harder charts, it would catch on with top-tier Japanese players. It didn't; most Japanese players prefer DDR and its chart style and music. The ITG scene is almost exclusively Western.
* MemeticMutation:
** KONAMI WILL SUE
** [[http://www.youtube.com/watch?v=QixDSEoxig0 800$ BOOM]] (Both players get the same score on "Liquid Moon" in a tournament's final round, but one player accidentally hits a mine right at the end of the song. The "$800" refers to the difference in prize money.)
* NonIndicativeDifficulty: Overall, the Driven course may be harder on Hard than on Normal. However, there is one part near the end of Monolith where, on Hard, there is a steady stream of arrows, and on Normal, there are only off-beat (blue) arrows. Combined with the mods in the course, these arrows are difficult to hit at all, while the stream on Hard is easier to read.
* ThatOneLevel:
** Utopia Single Expert 11. It's okay for the most part, until a third into the song the steps stop making sense for a while. See [[http://www.youtube.com/watch?v=tTQKbAyYy0o here]]
** Tell Single Expert 12. It's hated due to the fact it has nearly-impossible to hit jumps.
* StopHavingFunGuys: Don't bother saying anything about the game if you can't clear double-digit songs.
* SuspiciouslySimilarSong: Plenty based on ''DDR'' songs.
** The first game has "Disconnected" for "[=PARANOiA=]", "I Think I Like That Sound" for "Drop Out", "Hand of Time" for "Healing Vision", and "Pandemonium" for "Gamelan de Couple" and "Legend of MAX".
** The second has "Energizer" for "MAX 300", which even nicks the slow part of "neoMAX", a ''fan remix'' of "MAX 300". "Energizer" piles on the references to the MAX series especially thick. It's very likely named as it is due to "Energizer Max" batteries, it has a big jump followed by slow section in the middle (though it's longer and brighter than the slowdown in "The Legend of MAX" - the background video shows a ''[[RelaxOVision freaking field of flowers]]''), and the first sixteen steps of both the Medium and Hard charts are the same as the Medium chart from "The legend of MAX".
** Not every SuspiciouslySimilarSong in ''ITG'' is taken from ''DDR'' though. The second game has "Determinator" for "[[Music/FrankZappa You Are What You Is]]".
* ThatOneAttack: Determinator Single Expert 12.
* ThatOneBoss: Where to begin? Of course, any [=ZiGZaG=] song is definitely one.
** There's also "Disconnected Disco"
* TheyCopiedItSoItSucks: Opinions are divided on this issue.
