History VideoGame / MarioAndSonicAtTheOlympicGames

* SmartBall: At one point in the 3DS story mode of ''London 2012'', Omega, a highly-complex robot, is repaired by none other than Donkey Kong of all characters at one point.

* GettingCrapPastTheRadar: In the "Supporting Characters quiz" in London Party, one of the questions asks what [[Videogame/SonicRiders Jet the Hawk]]'s nickname is. One of the choices is "Hound of Hell".

* WhatHappenedToTheMouse: The rivals disappear without explanation on the Wii. The DS version has most of them become friendly [=NPCs=].

* AntiPoopSocking: The first two games will remind you to take a break, but the reminders happen more often than the breaks they recommend.

* ItsAlwaysMardiGrasInNewOrleans: ''Rio 2016'' has the Rio Carnival taking place during the Rio 2016 Olympic Games in the summer. Note that in real life, the Carnival takes place in February, which is in the winter.

* {{Mondegreen}}: In the rugby event in ''Mario & Sonic at the Rio 2016 Olympics Games'', Shadow says an innocent word which is pretty hard to hear[[note]]Most likely "caught" or "punt"[[/note]], which sounds like [[CountryMatters "cunt"]]. [[http://www.mirror.co.uk/news/uk-news/dad-bans-young-daughter-playing-8503247 A father threw away the game when his daughter misheard and learned the word]].

* EarlyInstallmentWeirdness: The first entry in the series is missing a few things that are constantly present in the other entries.
** Donkey Kong, Silver, Bowser Jr., and Metal Sonic as playable characters.
** Runblebee as the announcer.
** The Dream Events taking place in ''Mario'' & ''Sonic'' locales.

* HalfDressedCartoonAnimal: In ''Tokyo 2020'', the ''Sonic'' guys wear shirts, and still go pantless.

** ''Sonic at the Olympic Games - Tokyo 2020'' ([[UsefulNotes/IOSGames iOS]] and [[UsefulNotes/AndroidGames Android]]; third game in the series featuring only the ''Sonic'' cast, a new story, several new events, and a $10 price tag for full game)

* DeweyDefeatsTruman: ''Tokyo 2020'' is set in the summer of 2020 when the Olympics are happening, when in real life, months after the game was released, the Tokyo 2020 Olympics was postponed to 2021 due to the COVID-19 pandemic. This has led to jokes among fans about the game being set in an ideal AlternateHistory where there's no pandemic.

%%* UnexpectedCharacter:
%%** Considering that these games have featured mainly the most important characters from the series, Nabbit's appearance in ''Rio'' came as a bit of a surprise.
%%*** Similarly, Zazz and Zavok from ''VideoGame/SonicLostWorld''.
%%** Same goes for the Boom Booms that have joined your team in ''Rio'', though to be fair, they've been around since the NES era.
%%** Jet and Wave could qualify, as they've only been highly featured in the VideoGame/SonicRiders spinoffs.
%%** Possibly the most extreme case on the Sonic side is Sticks, who previously only appeared in ''WesternAnimation/SonicBoom'', which is an alternate continuity of the Sonic series.
%%** Perhaps an instance where the unexpectedness is a ''lack'' of characters, four of the seven Koopalings have been shown, with Morton, Iggy, and Lemmy nowhere to be seen, making this one of the [[VideoGame/MarioIsMissing few]] times the Koopalings don't all show up.

** Donkey Kong, Silver, Bowser Jr., and Metal Sonic as playable characters
** Runblebee as the announcer
** The Dream Events taking place in ''Mario'' & ''Sonic'' locales

* MythologyGag:
** The devs remembered that [[SuperDrowningSkills Sonic can't swim]]; in water events he's the only one who wears a life jacket, stands up and falls into the water instead of properly diving, and just splashes his arms and moves himself forward instead of actually swimming.
** Mario and Bowser's team win animation ends with them assuming the same pose they have in the "Mario and Bowser" puzzle from ''VideoGame/StreetPassMiiPlaza'' (which itself is based on their artwork from ''VideoGame/DanceDanceRevolutionMarioMix'').

* DeweyDefeatsTruman: ''Tokyo 2020'' is set in the summer of 2020 when the Olympics are happening, when if real life, the Tokyo 2020 Olympics was postponed to 2021 due to the COVID-19 pandemic. This has led to jokes among fans about the game being set in AlternateHistory where there's no pandemic.

* MercyMode: In ''Tokyo 2020'', if you fail a mission 3 times, you can skip it.

* ''Mario & Sonic at the London 2012 Olympic Games'' ([[UsefulNotes/{{Nintendo 3DS}} 3DS]] and UsefulNotes/{{Wii}})

* ''Mario & Sonic at the Rio 2016 Olympic Games'' (Arcade, UsefulNotes/WiiU and [[UsefulNotes/{{Nintendo 3DS}} 3DS]])

* ''Sonic at the Olympic Games: Tokyo 2020'' (MobilePhoneGame spinoff featuring only the ''Sonic'' cast, a new story, several new events, and more features)

** The devs remembered that [[SuperDrowningSkills Sonic can't swim]]; in water events he's the only one who wears a life jacket, and the only one in Swimming who stands up and falls into the water instead of properly diving and just splashes his arms and moves himself forward instead of actually swaimming.

** The devs remembered that [[SuperDrowningSkills Sonic can't swim]]; in water events he wears a life jacket and runs on the bottom of the pool instead (even though [[ViolationOfCommonSense it makes no sense]] and is [[WhatAnIdiot actually ''against'' the rules]]). This is also present in ''London 2012''.

* VillainTeamUp: Bowser and Dr. Eggman do it on three different occasions in the ''Vancouver 2010'' DS game, the ''London 2012'' 3DS game, and the ''Rio 2016'' 3DS game. Their [[TheDragon Dragons]], Bowser Jr. and Metal Sonic, do this too in ''Vancouver 2010''.

* RealityEnsues: In ''Tokyo 2020''. [[spoiler:Turns out, keeping a handheld game console on all day drains the battery, just as it would in a real world.]]

** Luigi's boost in the ''Vancouver 2010'' is essentially the Green Missile from the ''VideoGame/SuperSmashBros'' series.
