Trivia / Love Live! School idol festival

• Defictionalization:
  • The voice actresses are gifted with their character's costume in the International Promo UR set.
    • Ai Furihata received Ruby's hanbok and wore it during the Korea fan meeting.
    • Anju Inami received two versions of Chika's cheongsam from Taiwanese fans.
    • Kanako Takatsuki received Hanamaru's chut thai during her visit to Bangkok.
    • Shuka Saito received You's cheongsam during the Shanghai Fan Meeting.
    • Aina Suzuki received Mari's cowgirl costume during Aqours' Beyond the Pacific concert.
    • Suwa Nanaka received Kanan's khaki suit when she appeared as a guest at Madman Anime Festival 2018 in Melbourne, Australia.
  • An card box resembling the yellow scouting box was released on July 13, 2018. It is stated to play sounds lifted from the game, and contains 11 random cards that look like the in-game envelopes plus 11 character cards.
• Genre Popularizer: School idol festival essentially codified the concept of a gacha rhythm game, with many, many games in years after following the same basic model set by the original SIF: rolling the gacha for high-rarity cards, short stories associated with those high-rarity cards, scoring being based not just on player performance but also card parameters, and limited-time events that reward players for finishing above specific ranking percentiles.
• No Export for You:
  • Several promotional cards were included with merchandise that was never sold outside of Japan. Some of these cards have been added to the sticker shop for international players, but most are completely unavailable. Though since promotional cards tend to be weaker than regular cards and often have Off-Model artwork, it's debatable whether this is necessarily a bad thing for anyone who isn't a completionist.
  • Love Live! School idol festival ~after school ACTIVITY~'s arcade version is Japan-only, due to the logistical issues (the network elements being a major component) and concerns over whether the game would generate enough revenue for operators to buy (in addition to licensing) inherent in trying to export Japanese arcade games.
    • This has been subverted after it was announced that the Arcade-Perfect Port of SIFAC for the PlayStation 4 will launch globally with an English language option alongside the Japanese version of the game. It's been speculated that the global success of the other Love Live! games in the franchise contributed to this decision.
    • Eventually even this would be subverted after the arcade versions online network capabilities were discontinued in 2021, with SIFAC cabinets finding their way onto American and European soil available to play at arcades that specialize in importing Japanese games, with one cabinet currently standing at the National Video Game Museum in London. However, the game is only playable in its free play state, meaning progress isn't able to be saved and cosmetic features such as unlockable costumes and stages cannot be accessed.
• Portmanteau Series Nickname: Sukufesu (スクフェス), from the "School" and "Festival" parts of the title. In English, it would be written as "SchooFes", although in practice very few English-language players call it that, opting to write "LLSIF" or "SIF" instead.
