History YMMV / RhythmHeaven

** The idol who performs in Fan Club from ''Heaven'' is unnamed and is only referred to as [[EveryoneCallsHimBarkeep Pop Singer]] in-game.[[note]]The French and Italian localizations do actually give her an official name. In Spanish, she is referred to as Anita Dynamite, and in Italian, she is named Corin Pop. That said, these names are likely non-canon since she is unnamed in most versions of the game, including the Japanese original (where she is just referred to as "Idol").[[/note]] Many fans, however, have decided to give her the name "Erina" after Hashiguchi Erina, who sang as her in the Japanese version of ''Heaven''. Likewise, the redesigned Pop Singer from ''Megamix'' is named "Arisa" by the fandom after Hario Arisa, her voice actress in the Japanese version of ''Megamix''.

** The music in ''Heaven's'' Love Lab and ''Megamix's'' Pajama Party are ''extremely'' similar, especially the singing in the two. Thus, it's a popular fan theory that the girl in Pajama Party is the child of the couple from Love Lab.
** The Pop Singer in ''Megamix''[='s=] incarnation of Fan Club is intended to be a redesign of the Pop Singer from ''Heaven'''s version of Fan Club. However, fans opt to interpret them as two separate characters instead due to their different designs and different voices in Japanese (the Pop Singer was voiced by Hashiguchi Erina in ''Heaven'' and Hario Arisa in ''Megamix'').[[note]]The English localization simply reuses the English vocals from the ''DS'' version.[[/note]]

** The ''Rhythm Heaven'' and ''VideoGame/WarioWare'' fandoms tend to be incredibly close and interconnected with each other due to both being incredibly similar in terms of overall style and gameplay (despite their different genres), on top of sharing many of the same devs between both games (including Ko Takeuchi, who designs the characters in both games). It helps that both franchises are [[SharedUniverse implied to share the same setting]], with characters from both franchises frequently crossing over into each other.

* MorePopularReplacement: The incarnation of Pop Singer from ''Megamix'' has become far more popular amongst fans than the original incarnation from ''Heaven'', as many found the new Pop Singer to be far cuter and to have more personality than the original incarnation.

* TheyWastedAPerfectlyGoodCharacter: Despite ''Megamix'' being touted as a celebration of the series' history and being the first game to have a full-fledged story mode, none of the franchise's large cast of characters are present in ''Megamix'''s story mode, which instead focuses on an entirely new cast of characters completely disconnected from the rhythm games. While this is an understandable choice, given the sheer size of the cast, many fans are disappointed that the game passed on an opportunity to flesh out the pre-existing characters outside of the rhythm games. Especially given how interesting a lot of them are.

* ReplacementScrappy: Many fans of ''Heaven'' do not like the redesigns for the Dazzles in ''Megamix'', feeling that basing them off of real-life actors makes them [[UnintentionalUncannyValley come off as jarring]] compared to the more cartoony art-style of the rest of the game.

* TheyWastedAPerfectlyGoodCharacter: Despite ''Megamix'' being touted as a celebration of the series' history and being the first game to have a full fledged story mode, none of the franchise's large cast of characters play a role in ''Megamix'''s story mode, which instead focuses on an entirely new cast of characters completely disconnected from the rhythm games.

** The idol who performs in Fan Club from ''Heaven'' is called Pop Singer. Many fans however, give her the name "Erina", after the idol, Hashiguchi Erina, who sang as her in the Japanese version of the game. Likewise, the redesigned Pop Singer from ''Megamix'' is named "Arisa" by the fandom, after the idol, Hario Arisa, who voiced the pop star in the Japanese version of ''Megamix''.

** The Pop Star from ''Megamix''[='s=] incarnation of Fan Club is intended to be a redesign of the Pop Star from ''Heaven''[='s=] incarnation of Fan Club. Due to their different designs and voices (in Japanese) however, many fans interpret them as being two separate characters instead.

* CultClassic: The series manages to have a very dedicated audience, despite only having four games and being easily overshadowed by its sister series, ''VideoGame/WarioWare''. This only really applies to the west however, as the franchise is far more popular in its home country.

** One debate that is present in both this fandom and the ''VideoGame/SuperSmashBros'' fandom, which character should join ''Smash''? It is well agreed amongst both parties that a ''Rhythm Heaven'' character is deserving of being in ''Smash Bros'', but fans of either can't seem to agree on ''who'' should join and given the ''massive'' cast of characters, it's not hard to see why. The most nasty debates however tend to be between fans of Karate Joe and fans of the Chorus Kids, with fans of the former finding him to be a more natural fit for Smash given that he is a fighter, on top of being one of the few characters that has appeared in every game in the series, while fans of the latter feel Chorus Kids would be suitable as a Rhythm Heaven rep due to their explicit music theming, on top of the Gematsu Leak listing them as the Rhythm Heaven character [[WhatCouldHaveBeen planned]] for ''Smash 4'', supported by DummiedOut files listing the series amongst universes with fighters in the game and a Smash Run enemy where every other mob in that mode was tied to either Smash or a fighter in the game (including Ice Climber's, who were also cut from the game). There are also fans who TakeAThirdOption and feel the Girl from Tap Trial or Tibby from ''Megamix'' would be the best contenders for ''Smash'', due to the former traditionally acting as the SeriesMascot (on top of adding more female representation to the series) and the latter being the closest the series has to a central protagonist.

Fans have taken to putting this into other rhythm games and/or proving that it is, in fact, possible to beat.[[/labelnote]]

** Many fans interpret the boy from Kung Fu Ball as being [[VideoGame/WarioWare Young Cricket]], due to their highly similar designs. This would later become AscendedFanon come Young Cricket's character trailer for ''VideoGame/WarioWare Gold''. His partner from said game is occasionally portrayed as a friend or love interest, often being named "Young Dragonfly"- though ''Get It Together'' would officially name her as Cicada.

* SuspiciouslySimilarSong: The beat for Bunny Hop matches a bit too well with Mike's theme from ''VideoGame/WarioWare Touched''. [[https://gilvasunner.bandcamp.com/track/mikes-bunny-hop Demonstrated here]] by Music/SiIvaGunner. It also sounds similar to Greased Lighting from ''Film/{{Grease}}'', demonstrated [[https://soundcloud.com/poyo-poyo-pwayo/greased-bunny here]].

* PortingDisaster: There was once a bootleg iOS port of ''Megamix'' (which refers to itself [[BlatantLies as one to ''Fever'']].) that was predictably full of issues such as the removal of story cutscenes, input delay and framerate issues, the music being glitched, a number of Rhythm Games being removed, and according to a playthrough of the port, [[FromBadToWorse it contains Malware]]! Eventually and thankfully the port was removed, making it no longer accessable.

** "Monkey! MONKEY HAHAHAHAHAHAHAHA!"[[labelnote:Explanation]]In May 2020, Timotainment streamed a playthrough of ''Fever''. When he got to the first minigame, Hole in One, he is greeted with a monkey. Before the monkey introduced himself, Tim called him a monkey, and hysterically laughed after he did.[[/labelnote]]

* IAmNotShazam: Many people refer to the lizards from Love Lizards as, well "Love Lizards", when they're actually called '''Güíro''' Lizards. What doesn't help is that one trophy description from ''VideoGame/SuperSmashBros'' also called them "Love Lizards".

%%Zero-Context Example; too vague and general. * ThatOneAttack: With many a level, there's usually one segment that's especially hard to nail, either due to tight timing, really fast prompts, or both at the same time. The game's aware of these moments too, and prone to denying your Superb if you don't get them right. ''Megamix'' also likes to place its Skill Stars there too.

** 'Man, Suki's gonna die...'/'She must really hate Suki.'[[labelnote:Explanation]]Before ''Fever'' was localized, fans of the Japanese Love Rap would choose to interpret the lyrics as a song about wanting to kill a girl named Suki, as the main song lyric is "Daisuki!" Once the English version was released, fans started joking that the singer got over her hatred of Suki.[[/labelnote]]
