YMMV: osu!

  • Broken Base: Whether osu! is a Japanese or Western game, mostly: demonstrated brilliantly by I Can Be Your Friend
    • From what can be seen, the main discussion is whether or not the overabundance of Anime Theme Song beatmaps is a bad thing.
    • Storyboard toggles, skin toggles, and black backgrounds are argued as either necessary for competitive players, or ruining the creativity within osu!. Peppy, the creator, has claimed he will never add a full toggle on any creative elements without having some sort of condition, which of right now is having to play the map at least once with everything toggled on.
  • Fan Nickname: peppy is occasionally called pepsi. Also, osu! users can add their own nicknames to their "highlights" list.
  • Fandom Rivalry: With various other Rhythm Game series. Fans of other series scoff at the excessive number of Anime Theme Songs, scoring that is based excessively on combo and modifiers, and lack of original content. Players of osu! defend the user content-based gameplay and the fact that the game is free.
  • Germans Love David Hasselhoff: This game, made by someone from Australia, has huge fanbases in North America and Japan.
    • In fact, osu!'s community is very diverse, and you'll find players from a majority of developed countries in North America, South America, Europe and Asia, but not too many players from Australia. Not even anyone in the top #100 players in Performance Points are from Australia!
  • Memetic Mutation:
  • Narm Charm: The reason NotShinta's Aha? is actually liked by some people.
  • Scrappy Mechanic:
    • osu! is meant to simulate Ouendan and EBA. Unfortunately, this includes whatever Scrappy Mechanics the source games have, including spinners (which beatmap creators seem to be obsessed with, especially when making harder maps) and the very, VERY combo-based scoring system.
    • Now maps that abuse spinners are considered unrankable (it doesn't stop some maps occasionally being ranked when they have overly long spinners). Also, now there is the pp system, that balances scores between maps with a wide variety of max combos (but also makes plays that aren't Full Combos almost always worthless).
    • Modifiers multiply your score. One of these modifiers multiplies the speed of the song by 1.5x to give a score multiplier of 1.12x. So, to get a top-ranking score, you have to use it, which not only artificially inflates the difficulty of the beatmap, but also will probably make the song sound terrible.
    • More than a few players would like the option to toggle hitsounds and/or backgrounds unconditionally, a feature peppy is unwilling to implement (as mentioned above).
    • Playing with a mouse is this for some players, particularly those who can't afford a tablet or a touchscreen, due to the worrying potential to get carpal tunnel syndrome.
  • “Stop Having Fun” Guys:
    • Can happen sometimes with overzealous players.
    • Don't you dare farm AR 8 maps with Double Time, it proves you have no skill.
    • How dare maps without Insanes get ranked, they have no Performance Point value!
  • That One Boss: Can happen with any player on any song.
    • This version of Team Nekokan's "Can't Defeat Airman" has become a meme within the osu! community itself as being "That One Song." Despite being easier than Blue Dragon's version or Sushi's version, it is still considered very difficult to pass.
      • Part of the reason for this is that the beatmap in question is one of the first ever made, and contains many elements that border on Fake Difficulty, such as smaller circle size, low Approach Rate, inconsistent spacing, and a rather high slider velocity. None of these elements would be found in a so-called "Normal" difficulty today.
      • It is also required to pass this map in order to get an achievement for completing every song in the "Video Game Pack No.1" map pack. Since this is the only song in the pack with one difficulty, and passing it is not easy for Novice players, quite a bit of wrath is generated in the process of trying to beat it.
