* CultClassic: Due to its insane difficulty and similarity to the original ''Super Mario Bros.'', it doesn't get as much universal love as the other games in the series. Those who do love it, however, really love its challenge and don't accept "''Super Mario USA''" as [=SMB2=].
* ItsTheSameNowItSucks: Wasn't just a fan reaction. The #1 reason Nintendo decided not to export the Famicom version to the US was that they didn't think such an obvious MissionPackSequel would sell well in the States (note that simply being NintendoHard didn't stop them from exporting any other games back then).
* PainfulRhyme: The poem you get after beating 8-4, which also appears in ''Vs. Super Mario Bros.'':
-->Peace is paved/With kingdom saved/Hurrah to Mario[[note]]or Luigi, but that breaks the rhyme[[/note]]/Our only hero/This ends your trip/Of a long friendship[[note]]100000 pts. added/For each player left.[[/note]]
