History Trivia / Arcaea

* SimilarlyNamedWorks: The song "Singularity" by ETIA. shares the same name with a song by Music/{{Vocaloid}} producer keisei. This actually created a problem when the former was crossed over into ''VideoGame/GrooveCoaster'', due to the latter song already being in the game; the problem was fixed by renaming the newer song as "Singularity -Binary Enfold-", referring to the ''Arcaea'' DLC pack it was introduced in.

* FollowTheLeader: This game's Potential mechanic seems to have inspired similar "2-decimal player rating that can increase or ''decrease'' based on recent performances" systems in other mobile rhythm games, such as ''VideoGame/{{Lanota}}'' and ''Phigros''. While arcade games ''VideoGame/{{maimai}}'', ''VideoGame/{{CHUNITHM}}'', and ''VideoGame/{{jubeat}}'' already have such systems, ''Arcaea'' is one of the first games on mobile to do it.

* ShortRunInPeru: The song "Auxesia" was first available to play in-game at Comiket 92 in Japan, on August 10 and 11, 2017. Note that most of the core staff is based outside of Japan. For 300 yen, visitors could purchase an unlock code that unlocked the song for their in-game accounts. Everyone who didn't go to Comiket or at least had a friend who could buy them an unlock code and send it to them had to wait until August 20, 2017 to buy the song.

** "Ikazuchi", and "World Vanquisher" make their non-Asia Pacific debut. Previously, those two songs could at least be played in countries that carry ''VideoGame/{{maimai}}'' due to crossing over to that game. "Garakuta Doll Play" made its U.S. debut in ''VideoGame/GrooveCoaster 2: Heavenly Festival''.

* PromotedFanboy: Several members of the development team are already fans/players of {{Rhythm Game}}s themselves, most notably ''VideoGame/GrooveCoaster'' and ''VideoGame/{{CHUNITHM}}'' which the game had crossover events with. Ironically, none of the core team is based in Japan, [[NoExportForYou which is the only country that the latter game can be played in]], and ''CHUNITHM'' in particular is one of the most demanded Japan-only games by the non-Japan rhythm game community. Even more ironically, the 2020 version of the ''Arcaea''/''Chuni'' crossover adds more of the former's songs to the latter, and several members of the Arcaea team are based in the United States, which came under a near-global travel ban due to its poor handling of the UsefulNotes/CoronavirusDisease2019Pandemic, meaning that the American side of the team won't get to play the ''CHUNITHM'' charts of their own game's songs for a long time.

* TrollingCreator: Promotional material for the ''CHUNITHM'' collaboration clearly describe Nono's skill, which awards a whopping 2,525 Fragments for getting an EX rank. [[spoiler:What said material doesn't tell you is her Frag stat of 0.5, multiplying that bonus by 0.01.]]

* FanworkBan: Seemingly uniquely among rhythm games, Arcaea's derivative works policy forbids the practice of using Arcaea songs in custom charts for other games (such as VideoGame/StepMania). This is most likely to be a measure against VideoGame/{{Osu}}, which by taking donations is technically for-profit, but does more damage to the regular hobbyist charter than anyone else.
