History Trivia / SuperMario3dWorld

** With the first ''VideoGame/{{Knack}}'' game, which was released a week or two later, depending on territory. ''Knack'' got worse reviews than this game, but actually sold a fair bit better between its launch and around Christmas 2013. Though this game would ultimately outsell ''Knack'' quite handily, many agree in retrospect that this was the point when it became obvious that the UsefulNotes/WiiU was going to lose [[UsefulNotes/TheEighthGenerationOfConsoleVideoGames its console generation]], '''badly'''. The ''Mario'' franchise would subsequently get payback in 2017, when ''VideoGame/SuperMarioOdyssey'' handily demolished ''Knack II'' in sales.

** People actually guessed [[spoiler:a playable Rosalina]] after getting a look at a screenshot that showed outlines of all the possible stamps for use on Miiverse. That screenshot showed that there were five icons that resembled the player character icons used in the user interface (Player selection and life counter).
** People also guessed [[spoiler: Cat Bowser as the FinalBoss.]]
** The announcement of a UsefulNotes/NintendoSwitch port surprised no one, given that not only [[ContentLeak had it been leaked months prior]], but also that essentially every UsefulNotes/WiiU game was being ported to the console. The announcement of the Switch port happened several weeks after another Wii U game was announced to be coming to the Switch, that game being ''VideoGame/Pikmin3''.

** Like its [[VideoGame/SuperMario3DLand predecessor]], the game was originally going to have a stereoscopic 3D feature but it was dropped due to the fact that it wouldn't have worked well with the multiplayer mode, since each player would require their own set of 3D glasses. This would've made it the reason the game is called ''Super Mario 3D World'' than just because it's the sequel to ''Super Mario 3D Land''.

** The team originally considered having Yoshi as a playable character at one point, however this idea was scrapped due to much of his moves being too similar to other functions of characters and items, such as Peach's floating, the Piranha Plant's chomping, and Plessie's riding abilities.

** In commemoration of Advertising/TheYearOfLuigi (which celebrated Luigi’s 30th anniversary), The Wii U original contains a special version of ''VideoGame/MarioBros'' called ''Luigi Bros.'', as well as [[https://www.mariowiki.com/List_of_Luigi_sightings_in_Super_Mario_3D_World numerous Luigi Easter Eggs]] throughout the game. These were actually retained in the Switch port, despite lacking the context for their addition at the time.

** The Switch port was one of the three major titles released during the 35th anniversary of ''VideoGame/SuperMarioBros'' (the other two being ''Super Mario 3D All-Stars'' and ''VideoGame/SuperMarioBros35'') and like the other two, was announced in a special anniversary direct.

* NewbieBoom: The original Wii U release sold about 5.88 million copies by the end of the console's lifespan. The Switch port sold close to 11 million copies by the end of 2022. This was chalked up to both the larger install base of the Switch console and the added ''VideoGame/BowsersFury'' mode bringing in a ''lot'' of interest when it was revealed.
