* BigInJapan: The games have apparently done ''very'' well in the Japanese market, enough to prompt a CompilationRerelease for PS Vita and [=PS4=]. It [[ColbertBump probably helps]] that Creator/{{Suda 51}} is [[OneOfUs a fan.]]
* ColbertBump: Most of the artists on both games' soundtracks saw a huge popularity boost. The same went for the synthwave/darkwave genre, which was rather obscure but is now deeply associated with 80's aesthetic sensibilities and ultraviolence.
* FanNickname: Due to the game's use of a NamelessNarrative, fans have come up with a number of nicknames for the main characters for the sake of convenience. [[AscendedFanon Some of them were eventually adopted by the developers as semi-official nicknames.]]
** The main protagonist is known as ''[[IconicOutfit Jacket]]''. This nickname is popular enough that it is what the character is known as in his role as a GuestFighter on ''Videogame/{{PAYDAY 2}}''.
** The man in a motorcycle helmet is known as ''[[BadassBiker Biker]]''.
** The DamselInDistress is known as ''[[HookerWithAHeartOfGold The Hooker]]'', or ''[[ImpliedLoveInterest Girlfriend]]''.
** The hairy, bespectacled clerk is known as ''[[WildHair Beard]]'', ''[[MuggleBestFriend The Friend]]'', or ''[[spoiler:The Soldier]].''
** All the characters who wear masks, while officially unnamed, are generally referred to by the name of their corresponding mask, such as ''Richard the Rooster'', ''Don Juan the Horse'', ''Rasmus the Owl'', and ''Richter the Rat''.
* LyingCreator: [[spoiler:Dennation repeatedly went on record stating that ''Wrong Number'' would be the last entry in the series. Despite this, a secret [[TheStinger stinger]] after the second set of credits hints at a ''"Hotline Miami 3".'']]
* NoExportForYou: The second game was [[UsefulNotes/MediaClassifications refused classification]] in Australia due to an implied rape scene, thus making it illegal to sell there. The developers then turned around and told Australians to [[DigitalPiracyIsOkay pirate their game]].
* WhatCouldHaveBeen:
** The game was originally titled ''Cocaine Cowboy'', after the [[Film/CocaineCowboys Miami drug trade documentary]].
** An unused talking mask resembling [[Videogame/{{PAYDAY 2}} Hoxton]] can be found in the files of the second game, in reference to the collaboration between Dennation and Overkill.
** The soundtrack was going to have music from [[Film/{{Drive}} The Chromatics]], but their licensing costs were well outside of Dennation's budget, forcing them to look at more obscure artists. This probably ended up a good thing since, as noted above, the game's success gave a massive boost to the artists featured on the soundtrack.
