History YMMV / MarioAndSonicAtTheOlympicGames

* FandomRivalry: With the release of ''VideoGame/MarioPlusRabbidsKingdomBattle'' a rivalry of sorts has been brewing between the two series. [[FriendlyFandoms Fans]] of the ''Super Mario'' and ''Sonic the Hedgehog'' franchises have become extra bitter that their two favorite series and mascots and beloved characters have been considerably downplayed and have yet to receive a proper crossover with a story and is instead regulated to what they consider [[MinigameGame a collection of sports minigames]]. Meanwhile, ''Kingdom Battle'', with its completely [[BizarroEpisode insipid and insane setup]] still manages to have a plot is viewed as being very creative, having a ton of personality and charming interaction between the two universes, and regard it as a cruel twist of fate or a case of what a Mario/Sonic crossover should be, making them extra angry at the game and ''VideoGame/RavingRabbids'' series as well. This may be a case of GrassIsGreener however, and not actually hating the game itself.

* HarsherInHindsight: ''Tokyo 2020'' became awkward when the Olympics that year got postponed to 2021 due to the COVID-19 outbreak.

** The ending of ''Tokyo 2020'''s story mode has [[spoiler:the video game Sonic, Mario, Eggman, Bowser, and Toad are trapped in's battery slowly run out, which would make everyone trapped cease to exist. The battery dies just as an escape route is opened, causing the game world to fade into nothingness while everyone's speech fades in and out. While Eggman yells at everyone to hold on, no one can move, and they slowly dissolve into a single pixel as the screen flickers and goes dark, taking them with it... They all get better, though.]]

** The Hammer Throw event in ''London 2012'' has the characters letting out a [[ScreamingWarrior scream]] as they prepare to throw the hammer, which generally sounds as [[LargeHam over-the-top]] as you'd expect. When the character in question is Daisy, however, the scream sounds surprisingly realistic and blood-curdling.

* ToughActToFollow: ''Vancouver 2010'' and ''London 2012''. These two games [[GrowingTheBeard grew the beard]] and introduced many beloved features and characters to give the ''Mario & Sonic'' games a ton of personality and charm, [[EvenBetterSequel especially]] the handheld versions, which received solid acclaim. The Wii U entries ''Sochi 2014'' and ''Rio 2016'' had a lot to live up to and [[{{Sequelitis}} ended up with a far worse reception]] both by professional critics and fans.

* TheyWastedAPerfectlyGoodPlot: Although an interesting change, some people are disappointed that the 2D events in ''Tokyo 2020'' feature the Mario characters [[VideoGame/SuperMarioBrothers in their appearance in the original Super Mario Brothers for the NES]] while giving the Sonic characters their appearance from the Genesis games. Some people wish they could've used 16 bit graphics from ''Super Mario All-Stars'' instead (as Mario, Luigi, Peach, Bowser, and Toad appear in those too) to even out the graphics, or that the ''Sonic'' characters used sprite work based on the 8-bit Sega Master System and Game Gear entries. Though likely the developers were trying to go for the characters earlier appearances to fit the "trapped in the past" plot. [[note]] Mario was made in 1984 while Sonic wouldn't appear until 1991. His Master System incarnation only coming later.[[/note]]

** ''Tokyo 2020'' was also lackluster to some for how barebones the single player experience is (the Quick Match mode is pretty all there is to it), the removal of Miis, custom music remixes, Tournament mode, and other features players loved in the previous games, the amount of Dream Events only being three, and lack of bonus content after completing Story Mode. It did not help that players had waited a long time over the skipped Pyeongchang 2018 Olympics and expected Sega to craft up something very spectacular for an Olympics happening in their country.

* BreatherLevel: In the later chapters of ''Tokyo 2020'''s Story Mode, when the events get very nerve-wrecking and you may have skipped some, fighting Jet in the Football Kickoffs is very easy, as Jet's goalie will often make no attempt to block your ball and Jet will often kick the ball straight into you.

** This series is not the first time Nintendo has made an Olympic themed game. They previously made an Olympic themed game about {{Anime/Hamtaro}} called ''Hamtaro: The Ham Ham Games''. What’s more, the game was made by AlphaDream, who helped with the ''Tokyo 2020'' iteration.

* MST3KMantra: In full effect considering why the characters from both rosters would crossover for the Olympics of all places. (Does not count [[VideoGame/SuperSmashBros Sonic occasionally fighting Mario, Luigi, Peach, Bowser, DK, Diddy, Rosalina, Wario, Yoshi, Bowser Jr., the Koopalings, Dr. Mario, and Daisy every now and then]].)

* UnexpectedCharacter: Quite a few in some cases, namely Jet, Eggman Nega, and Dry Bowser in ''Sochi 2014'', Espio, Wave, Sticks, Zavov, Zazz, Larry, Wendy, Nabbit (with Ludwig and Roy in the 3DS version) in ''Rio 2016''.
* WinBackTheCrowd: After the bare bones presentation of ''Sochi 2015'' and ''Rio 2016'' (least on the Wii U for the latter, the 3DS version was at least cited to be decent). ''Tokyo 2020'' finally put more effort into things by giving a pretty quirk Story Mode and the return of Dream Events. While reviews did cite that there were actually fewer characters in this one compared to ''Rio 2016'' and would've like more Dream Events and character selection for the retro style. It likewise is a vast improvement as well.

* UnexpectedCharacter: Quite a few in some cases, namely Jet, Eggman Nega, and Dry Bowser in Sochi 2014, Espio, Wave, Sticks, Zavov, Zazz, Larry, Wendy, Nabbit (with Ludwig and Roy in the 3DS version) in Rio 2016

* ToughActToFollow: ''Vancouver 2010'' and ''London 2012'' are steadily proving to be this for the series. These two games [[GrowingTheBeard grew the beard]] and introduced many beloved features and characters to give the ''Mario & Sonic'' games a ton of personality and charm, [[EvenBetterSequel especially]] the handheld versions receiving solid acclaim. The Wii U entries ''Sochi 2014'' and ''Rio 2016'' had a lot to live up to and [[{{Sequelitis}} ended up]] being [[ContestedSequel far more]] [[BrokenBase divisive]] games.

* ThatOneSideQuest:
** Many of The Olympic Challenges in The Bonus Prologue Story of ''London 2012'' 3DS can be quite tricky because they require expert skill.
** Many of the Plus Face Offs during Road To Rio in ''Rio 2016'' 3DS. The most notable ones would be Rosalina, Sticks and Dry Bowser since they need the most precise timing and skill.
** Several of the Carnival Challenges in the Wii U version of ''Rio 2016'' can become this since the price to enter them ''doubles'' with every failure, and unless you know all the tips (which are ''locked'' until you first hear them), you're likely to find a challenge that doesn't even make sense. How many people know what a Dump is in Beach Volleyball anyway?

* ScrappyMechanic: Characters being limited to certain events in the handheld versions, a trend that began with London and is continues with Rio. Being the mascots, Mario and Sonic are excempt from this rule. This extends to the guest characters being restricted to certain events in ''Rio 2016'' and ''Tokyo 2020''.

* ThatOneLevel: [[DownplayedTrope Downplayed in the 100m Freestyle minigame in the DS version of ''Beijing 2008''.]] Most characters require you to either rub horizontally, rub vertically, spin in a circle, or trace a semicircle. Vector requires you to trace a figure-8.
