History YMMV / LoveLiveSchoolIdolFestivalAllStars

* SpiritualSuccessor: ''ALL STARS'' has some visual and conceptual similarities to ''School idol paradise'', a µ's-oriented ''Love Live!'' RhythmGame for the UsefulNotes/PlayStationVita that was just a ''little'' half-baked and not quite fully-realized.

* EvilIsSexy: Lanzhu, especially when chapter 26 reveals her casual and summer training clothes. This also extends to her group, the School Idol Association, as [[spoiler:she has recruited [[MsFanservice Karin]] and [[GyaruGirl Ai]]]].

* WTHCastingAgency: Some fans were puzzled on why A•ZU•NA ended up being the genki subunit, given the track record of its members, and the fact that ''none of them'' are actually [[GenkiGirl Genki Girls]], personality-wise. In Ayumu and Shizuku's case, both have emotional ballads as their solos and are reserved, calm and mature. In Setsuna's case, some fans believe the raw strength and energy of her voice clashes too hard with the other members. Other fans take a more conciliatory stance, and note that the characters are multi-faceted enough that it's believable that they can perform as a genki unit - particularly so given Shizuku's nature as an actress, Setsuna's otaku tendencies, and Ayumu's status as Nijigasaki's center.

** Lanzhu's introduction was a chance to explore how the girls would deal with a truly antagonistic figure, something no group in the franchise had to do so far. Her personality is a perfect driver for future conflicts that the club members could face and her skill as a school idol means that the club would have to make an effort to defeat her in a fair battle. However, all those plotlines are unceremoniously abandoned halfway through the season: Nobody (save for Kasumi, who isn't treated seriously by the story) holds a grudge against her despite her terrible behavior and start treating her as just another FriendlyRival, and on the process, the idea that she has to be "defeated" is dropped. By the end of her character arc, she is treated no different than every other ObstructiveBureaucrat that showed up in a Love Live title before.

** Lanzhu has the dubious honor of being potentially the most divisive character ''in the franchise.'' Players who experienced her through the game's story have a large variety of viewpoints of her. There's outright hatred for her due to her actions towards the other idols, her incredibly self-centered ego, and the story's heavily preferential treatment for her. Meanwhile, fans who like her, tend to cite her narcissistic personality and AwesomeEgo, her stylish performances, songs and sense of fashion, and her addition to the game's storyline shaking up the ''Love Live'' formula in unexpected ways. Curiously enough, this has led to a phenomenon where fans of ''ALL STARS'' Lanzhu seem to dislike anime Lanzhu getting "defanged" and becoming mostly a friendly rival to the Nijigasaki girls, which they blame on the poor reception of Season 2 of ''ALL STARS'' and what they call "complaining fans that couldn't handle a bit of conflict/drama".

* SuspiciouslySimilarSong: When the extended preview of Setsuna Yuki's solo "CHASE!" was released with the Tokimeki RUNNERS reveal, jokes about it being a ''LightNovel/SwordArtOnline'' theme song started circulating. The song has general stylistic similarities to the ''SAO'' series theme songs, and Setsuna sounds somewhat like [=LiSA=] at certain points. It also helps that her voice actress' most famous role was as the protagonist of ''LightNovel/SwordArtOnlineAlternativeGunGaleOnline'', LLENN, and performed said anime's ending song.

** In the original Japanese, the main character's gender was significantly more ambiguous as the game enforced GenderNeutralWriting with a lean towards a female disposition; the implication that the player was explicitly female was only revealed later in the story. In the English translation, due to the inability to use gender-neutral pronouns, the protagonist's gender is outright stated to be female from the get-go.

* GameBreakingBug: The 3DMV fog effects which was first introduced in the songs "Queendom" and "WATER BLUE NEW WORLD" have caused significant framerate drops on moderate phones.
* GoddamnedBats: "Mijuku DREAMER" introduced "Maintain Stamina" Appeal Chances, which are the first [=ACs=] in the game that cannot be ended prematurely since its success condition requires fulfilling the target condition at the ''end'' of the AC. This means that you cannot force early successes through specific team comps, you must eat and heal the damage as intended to get the free points, and you don't get Star Notes out of them that grant bonus points and prevent you from taking damage. Particularly annoying since all other [=ACs=] in the game are considered "free" once you pass their checks and strategies can be routed around them safely.

** Then come in 2021, the ''Anime/LoveLiveSuperstar'' anime broadcast had its third episode delayed by UsefulNotes/SportsPreemption due to being broadcast on Creator/{{NHK}}-E which also happens to be the official Japanese broadcaster of the 2020 Olympics.

*** Ditto Karin's single on the third album, "Fire Bird", which shares the same title with one of [[Anime/BanGDream Roselia's]] singles.

* MemeticBadass: Kanan seems to consistently get extremely good or powerful cards, including both her first and second [=URs=] and her Fes card, considered to be the best scoring card in the game. Some fans joke that [=KLab=] is making up for her [[TheyWastedAPerfectlyGoodCharacter lack of meaningful screentime]] by making her overpowered.

** There are three types of defensive techniques: Healing, Shields, and Damage Reduction. Of these, you will rarely ever see anyone consciously run damage reduction, as it's generally the least efficient way of directly preserving Stamina, and it makes it counterproductive to run them in the same Subunit as Voltage cards due to the damage penalty that Voltage cards incur by simply existing. There ''are'' songs that enforce the use of damage reduction to not die, but these are few and far between compared to standard songs.

* TheScrappy: Lanzhu was hit hard with this while Season 2 was releasing. Owing to a streak of unpopular character and storyline choices, a conflict whose tone clashes with the rest of the franchise's own, and factors regarding the game's performance and quality, Lanzhu garnered a lot of enmity from a good part of the game's Asian fanbase. Comparatively, she's more of a BaseBreakingCharacter in the West.

** The intermission chapters introduce two new characters, Lanzhu Zhong and Mia Taylor, who were set up to become Nijigasaki's rival characters in Season 2. While not outright disliked for the most part, the initial reception to their characters through their introductory chapter was mostly lukewarm to cold, with a significant lack of appeal compared to the other rivals.

** Most of the Appeal Chances in "Yume no Tobira" Challenge, which deal massive unavoidable damage a la "Ketsui no Hikari" except this time it's equivalent of protecting a glass window from a cannonball shot point-blank.

** One of the SBL Goals required winning at least one of the 4 Skill Awards for 10 free Star Gems. This would mean only 9 tries a day competing against up to 9 other players in Global version or ''19 players'' in Japanese version at once aiming to come in first place. In addition to that, this would also mean that the players who were completing this mission were the ones who already had powerful teams in the first place, and were the ones who were least likely to be in need of Star Gems.

* TierInducedScrappy:

There ''are'' songs that enforce the use of damage reduction to not die, but these are few and far between compared to standard songs.
** Similarly, there are three types of direct offensive techniques: Appeal Boost, Voltage Boost, and Voltage Gain. Voltage Gain is typically the worst of the lot, as unlike Appeal/Voltage Boost, which raise Appeal/Voltage directly and can be applied to the whole strategy with the right builds, Voltage Gain simply takes a percentage of the card's stat and adds it to your Voltage as a flat number without scaling, making it contribute significantly less score than usual over the course of a song. "Scarlet Courage" Setsuna and "Secret Galaxy" Kanan are exceptions since their Appeal stat is so ridiculous that it makes up for having Voltage Gain as an Active.

* AuthorsSavingThrow:
** While the original ''VideoGame/LoveLiveSchoolIdolFestival'' game featured a PlayerCharacter protagonist, her existence was only acknolwedged for the first couple of chapters in the storyline and then dropped afterwards, with none of the characters even so much as acknowledging her past that point. This led some fans to question what the point was of such a character was to begin with. This was especially since she became a virtual non-entity shortly after the story begins, preventing players from even projecting themselves onto her as a self-insert. This game, however, includes such a character as an important part of the plot and gives her significant interactions with all of the school idols throughout.
** Ayumu was originally very aggressive and jealous towards the other members in the early {{Yonkoma}}s, an extremely bizarre instance of EarlyInstallmentWeirdness as she is a straightforward NiceGirl in current material. This was rectified in a comic where she was revealed to be the victim of DemonicPossession (ItMakesSenseInContext) and was exorcised by Nozomi, thereby aligning her more with her current personality.
** The absurd Silver Macaron grind was quickly addressed by [=KLab=] within a week of release, awarding 100 3★ Silver Macarons to all players and promising to tone down the required grind.
** A series of patches in October 2019 rebalanced the gameplay loop based on the complaints [=KLab=] received from players.
** Version 2.0.0 reworked a significant chunk of the story to remove a portion of the playable songs, often accused of padding; and beginning in Season 2, the song lists introduced two difficulty settings for average players to easily catch up the story. It also updated the Goals to remove the Weekly Goals that require playing the game, and updated Story Songs so that they now count towards Goals.
** Later DLP updates (January 2021 in JP, March in EN) started adding limited-time "easy" towers that are vastly less difficult than the regular Parades, making grinding out coins and earning DLP-specific rewards and Star Gems more accessible for casual players.
** Later chapters of Season 2 make it clear there was an attempt at this, as the story returns to a primary SliceOfLife focus. This is marked by a sharp pivot from treating the Association less like rivals into treating them more as an extension of the Club with creative differences, with basically all of its members except Lanzhu being portrayed in a sympathetic light and Lanzhu herself getting some fun interactions with the other cast members rather than just being antagonical.
** Following the less-than-positive reception to the opening chapters of Season 2, the story has made a point of softening Lanzhu's character. Her current character is only vaguely similar to her character at the start of the season, being a boastful and egotistical rich kid school idol, but her current character is [[TookALevelInKindness leagues nicer than before]] and [[IJustWantToHaveFriends driven by a desperation to forge real friendships]], rather than being a AlphaBitch who is [[LackOfEmpathy callous and insensitive to others]] and wants to be the best for the sake of it. The plot also attempts to HandWave her earlier behavior and some inconsistencies caused by this change, such as revealing that she's TalentedButTrained to justify the CharacterShilling and that her earlier treatment of the protagonist was borne out of jealousy of her. [[spoiler:She even admits to everything that she did wrong to the protagonist and the Club and delivers a sincere apology to both without any pushback whatsoever]].
** Chapter 28 tries to spin [[spoiler:Ai and Karin's]] decision to join the Association in a more positive light by showing a {{Flashback}} where they explain that [[spoiler:they didn't approve of how Lanzhu barged into the Club and tried to get them to join the Association, but they were moved by her passion for school idols and joined on as temporary members to get a feel for her methods. They make it clear that they were still dedicated to the Club but were willing to give the Association a chance due in part to both Lanzhu's passion and their personal desire to improve]].
** Fans theorize that this is what the writers are going for with Season 3, since the first three chapters are essentially {{Recap Episode}}s that discuss the events of the ''School idol project'' and ''Sunshine!!'' anime while not progressing the plot in any meaningful way in order to stave off the aftermath of the poorly-received Season 2.
** Recent updates eased up the difficulty of Season 1 and Season 2 Normal songs, making easier to clear them to catch up the story. The updates also made [=S1=] and [=S2=] songs playable in Live Shows for newcomers without going through the story just to unlock them.
** Birthday Scouting banners now guaranteed to obtain a UR card of a birthday idol a 100% chance in the final step from previously a luck chance.

* SeasonalRot: Season 2 of the game in general has negatively impacted fan reception to a fair degree. In addition to the aforementioned problems that fans have with the story, some questionable game design choices such as the huge {{Difficulty Spike}}s in playable songs, mostly stale event rotations, and the introduction of Party Gachas with some of the biggest PowerCreep jumps in the game's history has caused many Japanese fans to drop the game. The declining sales and player participation throughout Season 2 is strongly suspected to have caused [=KLab=] cutting ties with the game and passing it off to another developer, [=MyNet=] Games. Since then the game has mostly recovered from its slump and has become significantly more generous, but what's left of the game's fanbase after the Season 2 drama remains a shadow of its former self.

** A lot of problems that fans have with Lanzhu existed back with Shioriko in Season 1, including many of her extreme personality traits and antagonistic stance towards the Club. However, many fans gave Shioriko a pass because she wasn't anywhere near as excessive as Lanzhu and still generally fit the mold of "unwilling StudentCouncilPresident" common to the series. Focus on Shioriko also only intersected with the main plot when needed and she was later revealed to have redeeming qualities, ultimately [[spoiler:forging a close friendship with Ayumu and playing a critical role in the School Idol Festival's success]]. Lanzhu does ''none'' of these things, essentially being [[UpToEleven a worse Shioriko]] and an InvincibleVillain who quickly took over the story as soon as she arrived, greatly souring fans' perception of her compared to the former.

** Lanzhu has the dubious honor of being potentially the most divisive character ''in the franchise.'' Players who experienced her through the game's story have a large variety of viewpoints of her, be it outright hatred for her due to her actions towards the other idols, her incredibly self-centered ego, and the story's heavily preferential treatment for her. Meanwhile, fans who like her, tend to cite her narcissistic personality and AwesomeEgo, her stylish performances, songs and sense of fashion, and her addition to the game's storyline shaking up the ''Love Live'' formula in unexpected ways. Curiously enough, this has led to a phenomenon where fans of ''ALL STARS'' Lanzhu seem to dislike anime Lanzhu getting "defanged" and becoming mostly a friendly rival to the Nijigasaki girls, which they blame on the poor reception of Season 2 of ''ALL STARS'' and what they call ''crybaby fans that couldn't handle a bit of conflict/drama''.

Players who experienced her through the game's story have a large variety of viewpoints of her, be it outright hatred for her due to her actions towards the other idols, her incredibly self-centered ego, and the story's heavily preferential treatment for her, or blaming the writers and not the character for her faults and preferring to focus on her more positive aspects, such as her music, singing voice, and/or her (post-Season 2) personality and genuinely comedic interactions with the other club members.

** Continuing on from the original ''School Idol Festival'', Shizuku Osaka is once again shipped with Hilda from the ''{{Franchise/Pokemon}}'' games in crossover fan art as well as in the crossover fanfiction universe ''Fanfic/TokimekiPokeLiveAndTwinbee''. Joining Shizuku, Rina Tennoji is also involed in a crossover ship in Fanon as well, with her being shipped with Freya Jerbarn from the ''Xak'' series of games by certain people on [=DeviantArt=].

** The School Idol Festival being cancelled because of the Olympics is likely harder to stomach after the fact, considering the Tokyo 2020 Olympics themselves were delayed due to the COVID-19 pandemic.
** Then come in 2021, the ''Anime/LoveLiveSuperstar'' anime broadcast had itsthird episode delayed by UsefulNotes/SportsPreemption due to being broadcast on Creator/{{NHK}}-E which also happens to be the official Japanese broadcaster of the 2020 Olympics.

This game, however, includes such a character as an important part of the plot and gives her significant interactions with all of the school idols throughout.

* BrokenBase: Whether or not the Nijigasaki High School Idol Club qualifies as a "main" group is still a hotly-debated topic to this day. The main drivers of this split come from the [[BreakingOldTrends highly-unorthodox format]] compared to µ's, Aqours and Liella! and debuting in a game first instead of an anime/manga, as well as it's official designation as a "side project" despite receiving virtually the same treatment as all other groups (no doubt in part due to huge fan support). On one side, you have fans who will vehemently defend Nijigasaki as being equal to the other groups despite their "side project" status and [[FandomEnragingMisconception will not hesitate to call out anyone who says otherwise]], while on the other side you have fans who will outright dismiss their existence due to their differences despite the amount of media and attention dedicated to them and refuse to associate them with the other groups, typically referring to Liella! as the "true" third unit.

* UnintentionallyUnsympathetic: Lanzhu [[spoiler:being a BrokenAce is clearly meant to garner pity for her actions and the characters do certainly see it that way in-universe; however, to some readers her backstory simply comes off as shallow and in no way making up for what she did at the start of season 1.]]

** Some elements of Dream Live Parade are not particularly well liked, most notably the PP mechanic that makes up the core of the format. Cards can only be used a limited number of times per DLP, with most cards only being able to be used ''once'' and boosted cards up to twice. PP can be recharged, but only once free per event and up to three times maximum via Bottles and Star Gems. The mechanic's existence drags out both the time investment and difficulty by ''magnitudes'', as teams must be reformed ''per stage'' and you must plan extremely carefully to maximize card usage or else suffer early burnout and be forced to wait for the next DLP. Even worse, the mechanic inherently punishes players with fewer cards, especially those who save for long periods of time to pull on specific banners.

** One of the SBL Goals required winning at least one of the 4 Skill Awards for 10 free Star Gems. This would mean only 9 tries a day competing against up to ''19 other players'' at once aiming to come in first place. In addition to that, this would also mean that the players who were completing this mission were the ones who already had powerful teams in the first place, and were the ones who were least likely to be in need of Star Gems.
