History Trivia / DanceDanceRevolution

** DDR Extra Mix for the UsefulNotes/PlayStation has the DDR Solo 2000 pairs, but also features two instances of "Sky High": one by DJ Miko, and another by Lucyfer. Both songs are different.

*** The pan-Asian version, outside of Japan and South Korea, is even worse: it lacks the seven Japan-exclusive songs ''and'' the South Korean songs. With ''4thMix'', however, four of the Japan-exclusive songs were added.

*** In early 2022, Dave & Buster's Oakville in Canada disconnected its ''DDR A20 Plus'' machine from e-Amusement, further limiting the machine's functionality compared to offline European machines.
** ''Dance Dance Revolution A3'' remains unreleased outside of Asia, except for a few TDX cabinets in Hawaii. In the United States, ''DDR A3'' is only available as a Japanese import on golden cabinets at [=Round1=] USA. In Canada and Europe, the game is unavailable.

** Averted with ''Dance Dance Revolution A'' , and generally with ''Dance Dance Revolution A20'' and ''A20 Plus''. In 2016, North America received an official release of ''DDR A'' with e-Amusement support, including 62 arcades in USA (34 Dave & Buster's and 28 Round1) and Dave & Buster's Oakville in Canada. On December 15, 2017, Europe received an offline version of ''DDR A'', which was last updated on May 21, 2021 via an offline kit. As of July 15, 2023, 34 arcades in Europe offer ''DDR A'', and two others have upgraded their ''DDR A'' machines to ''A20 Plus''. This makes it one of the best selling ''DDR'' arcade games, though with fewer sales than ''DDR SuperNOVA''.

** ''Dance Dance Revolution A3'' remains unreleased outside of Asia, except for a few TDX cabinets in Hawaii. In the United States, ''DDR A3'' is only available as a Japanese import on golden cabinets at Round1 USA. In Canada and Europe, the game is unavailable.

** There are two different songs named Fantasy, one which debuted in MAX, and another ("STAY (Organic house Version)" from Dance Maniax 2ndMix) which debuted in [=MAX2=]. Yes, both are available on Extreme.
** There are two different songs named Stay, one which is exclusive to [=MAX2=], and another which became a mainstay after debuting in Extreme.

* LateExportForYou: Starting with ''A'', new arcade releases usually trickle down to North America a few months later, and in an offline form in Europe 1-2 years later. ''A3'' was an unusual case for North America because it was released in Japan and non-Japan Asia in March and June of 2022, respectively, and only the state of Hawaii got it out of the 50 states in June. The continental U.S. had to wait until August 2023, 14 months after Hawaii.

** Before ''A'', without counting region exclusive releases like ''Dance Dance Revolution USA'' or ''Dancing Stage [=EuroMix=]'', there were only 4 arcade installments that were released internationally: 1st Mix, [=SuperNOVA=], X, and X2. This led to almost every other arcade importing the games at the height of DDR's popularity and using bootlegged upgrades, with ''Extreme'' being the most common version even today.

** With no international release for X3, the arcade DDR landscape ended up back to how things were before [=SuperNOVA=], except with the added complication of e-Amusement. DDR 2013 and onwards will also refuse to boot if they are not connected to e-Amusement, unlike previous games where connectivity was optional, making importing only possible with bootlegged servers.
** This was zig-zagged with ''Dance Dance Revolution A'' and beyond, having official American releases at various [=Round1=] and Dave & Busters locations around the US, along with one in Canada, including e-Amusement. Europe was not as lucky, as, despite promises that it would happen eventually, there is no timeframe on whether there will actually be e-Amusement for that region. While America got A20 and A20 Plus, which were released via e-Amusement updates, Europe is still stuck with DDR A. There has yet to be a U region build of A3, meaning it is largely exclusive to the [=Round1=]-exclusive 20th anniversary cabinets, and white cabinets (located primarily in Hawaii) that run an uncommon "T" region build.
