History Videogame / Osu

** [[https://osu.ppy.sh/beatmapsets/871064 This map]] is so deranged Auto can't even 100% it!

Game levels, called beatmaps, are created and submitted by users via a LevelEditor. These can later be refined through community modding if the creator requests it and gets [[OfficialFanSubmittedContent ultimately approved]] by members of the Quality Assurance Team and Beatmap Nomination Group.

* FunWithAcronyms: GMT (Global Moderator Team), QAT (Quality Assurance Team).
** Also some, teams that don't exist anymore, like MAT (Modding Assistance Team), BAT (Beatmap Appreciation Team).

* PinballScoring: In standard mode, the maximum possible score of very long beatmaps with huge note counts can grow to very large numbers. In one extreme example, the very long "[[https://osu.ppy.sh/s/29157 Within Temptation - The Unforgiving]] described in MarathonLevel above has 10-digit scores in the top four ranks (as of this edit). To get good scores in any given map, getting a full combo is crucial. Tournaments instead use a "score v2" system with a maximum 1,000,000 points and avert this trope.

* NintendoHard: Thought ''VideoGame/EliteBeatAgents'' and ''VideoGame/OsuTatakaeOuendan'' were hard? You haven't seen anything yet. The hardest songs from Ouendan/EBA are approximately 3.5 stars on the revised star rating scale released in mid-2014, and these games are already Nintendo Hard on their own. The hardest songs on Osu takes this UpToEleven, with revised star rating exceeding 7 stars, such as [[http://osu.ppy.sh/s/24313 "Can't Defeat Airman"]]. Such crazy streams and jumps do not exist in the original Ouendan/EBA games. Certain maps can even have 10 to 11 stars.

* UpToEleven: Somewhat literally. There are 4 values for every map (Approach Rate, Overall Difficulty, Circle Size, and HP Drain) that the creator of the map can set from 1 to 10. The Hard Rock mod increases all of those ratings by a set amount, always maxing it at 10. The Double Time mod is an exception to this rule because it actually speeds the whole game up by 1.5x rather than directly changing the variables, this causes the game to play an [=AR10=] map at 1.5x speed, making it play as if the map had [=AR11=], even though their max is 10 in the game's code. [[https://youtube.com/watch?v=_VrkG_CAI1E This]] is what an [=AR11 OD11=] map looks like.
** Taken up to '''12''' in Taiko mode.[[note]]Each OD notch in Taiko decreases the hit windows by 3ms. OD10 in Taiko is 19.5ms, 13ms when time modded.[[/note]]

* LettingTheAirOutOfTheBand: Occurs on a failure. There's a grinding sound, and the music track slows down as it stops playing. Any visual beats also collapse and fade as well.

** On mapping side, it's HEAVILY discouraged nowadays, and maps with it have a very low chance of being ranked. Using solely tricks like low (or high) Approach Rate, high HP drain, etc., are no longer acceptable in the Ranked Beatmaps section. In addition, some very specific mapping techniques are not allowed to be ranked due to being very confusing and frustrating for players. A list of these can be found [[https://osu.ppy.sh/wiki/Unrankable_Techniques here]]

* AprilFoolsDay: The jokes each year revolve around changes in the game's genre ("Touhosu", a VideoGame/{{Touhou}}/osu! hybrid), gameplay ("osu!core", where the songs in every beatmap had their pitch and speed increased), staff (unexpected demotions or promotions), and beatmaps (pretending to approve and praise an extremely poorly made beatmap).

* AllLowercaseLetters: The game is called ''osu!'', and most of the community [[BerserkButton doesn't like it]] when people call it "Osu!" or "OSU". [[https://www.reddit.com/r/osugame/comments/4s7u0z/what_is_the_most_satisfying_thing_about_osu_for/d57mlzw Not even the main developer likes it.]]

* SelfImposedChallenge: Using one or more of the difficulty increasing mods and/or going for SS (perfect) runs.
** Playing with a "blind" skin is this, which is a skin with an invisible hitcircle. Players who use these kind of skins may also play with the Hidden mod, which hides the approaching circle.

** Playing for score? Aside from the combo multipliers practically encouraging restarting over one mistake (a game design element shared with ''osu!''' source game), modifiers add to your score, most notoriously the modifier that increases the song's speed by 50% to give a 12% score boost. So to get high-ranking scores you have to alter the song.

* UnwinnableJokeGame: Several maps, such as [[https://osu.ppy.sh/beatmapsets/150945 "Centipede" (Knife Party)]], are designed to be impossible for human players to full combo on, lest earn a "B" rank, with multiple circles to hit at the exact same time. Not that it means [[VisualEffectsOfAwesome the mentioned map isn't pretty to look at]].

* InterfaceScrew: The Hidden and Flashlight mods.

* CrossOver: The beatmap for [[{{Queen}} Queen's]] [[http://osu.ppy.sh/s/5381 Don't Stop Me Now]] is based on the plot of a FanFic which combines [[Franchise/AceAttorney Phoenix Wright]] with ''VideoGame/EliteBeatAgents''. It's as awesome as it sounds.

* PositiveDiscrimination:
** One reason is that Cookiezi, one of the top osu! players, is Korean.
*** In fact, even after he quit osu in May, he still was on top of the leaderboards until early September.
*** When he came back later during 2012, it took him about a week to recover the first place position.
** In Taiko mode, 2/3 of the first 100 ranks is occupied by Japanese players.
** One of the best osu!mania 4-key players is from Norway: Staiain.
