* CommonKnowledge: How exactly the remake caused [=AlphaDream=]'s demise. While the remake undoubtedly caused the company's bankruptcy, it wasn't the ''sole'' reason, just the final nail in the coffin. The studio was already entering debt in attempting to shift into HD and multiplatform development, and the previous attempt at solving the issue (''Superstar Saga + Bowser's Minions'') had middling sales that failed to resolve a worsening issue. ''Bowser's Inside Story + Bowser Jr.'s Journey'' was simply their final shot at attempting to fix this situation by skipping over ''Partners in Time'' to remake their most successful game.

* CommonKnowledge: How exactly the remake caused [=AlphaDream=]'s demise. While the remake undoubtedly caused the company's bankruptcy, it wasn't due to ''it'' that the company went bankrupt, it actually was the final nail in the coffin. Sales of the entire ''Mario & Luigi'''s series were flopping after ''Mario & Luigi: Paper Jam'' (its last million seller) and the company tried to make up for their losses by releasing remakes of their most successful games, however, by 2017 the 3DS was starting to be on its last legs (and the ''Superstar Saga'' ''Bowser's Minions'' remake, while somewhat successful, couldn't pay off their debt completely and sold less than a million copies); and by 2019 the 3DS was all but a defunct platform, with most people moving to the Switch instead. Releasing the ''Bowser's Inside Story'' ''Bowser Jr.'s Journey'' remake so late in the console's lifecycle proved fatal for them and became one of the worst selling ''Mario'' games of all time, not helped by a perceived unnecessariness, and failed to help [=AlphaDream=] make up for their losses that started after ''Paper Jam''.

* TheyChangedItNowItSucks: A number of the changes in this game's remake have garnered criticism, including the usage of unfitting voice clips for the Bros., unnecessary color changes in certain areas, and Bowser's punches no longer having the "oomph" they had in the original (in part due to him no longer [[PunchedAcrossTheRoom knocking enemies back several feet with an Excellent punch]]).

* SurprisinglyImprovedSequel: ''Partners in Time'' is generally considered a good game in its own right and by no means bad, but it's not considered to be as good as ''Superstar Saga'' and some fans consider it's weighed down by its inconsistent difficulty, pacing, a story that doesn't use either of its major hooks (time travel and an alien invasion) as effectively as they could have, and a lack of meaningful side content. ''Bowser's Inside Story'' dramatically expands on the combat of both prior games and smooths out the difficulty, makes incredible use of its dual-gameplay gimmick between Bowser and the Bros., and has a much more engaging story that works as an effective [[ADayInTheLimelight day in the limelight]] for Bowser. There are also actual sidequests and bonus bosses to add replay value.

** Whether or not the game needed a remake. Some say that the remake can stand on its own, providing a nice upgrade to the graphics and music, along with an improved sequel to ''Minion Quest'' in ''Bowser Jr.'s Journey''. Others believe there's no real reason for the remake to exist, considering the original game isn't exactly rare and can also be played on 3DS, and believe that the sprites and music of the original are better.

* SugarWiki/MostWonderfulSound: The Arm Station cannon shooting light orbs, followed by Mario and Luigi hammering them back to the rhythm. It's the main reason why its minigame is so fondly remembered by fans.

* SequelDifficultySpike: In comparison to ''Partners in Time''. While ''[=PiT=]'' was short, linear, gave you strong special attacks constantly, and was generally easier than the first game, ''BIS'' is longer, has a wide overworld with complex dungeons, has much more varied specials that actually cost a lot to use, and has some pretty tough fights (especially with the Challenge Medal equipped (only in the DS version)).

* SurprisinglyImprovedSequel: ''Partners in Time'' is by no means bad, but it's weighed down by a number of issues such as inconsistent difficulty, poor pacing, a mediocre story that doesn't use either of its major hooks (time travel and an alien invasion) as effectively as they could have, and a lack of meaningful side content. ''Bowser's Inside Story'' dramatically expands on the combat of both prior games and smooths out the difficulty, makes incredible use of its dual-gameplay gimmick between Bowser and the Bros., and has a much more engaging story that works as an effective [[ADayInTheLimelight day in the limelight]] for Bowser. There are also actual sidequests and bonus bosses to add replay value.

* UnintentionalPeriodPiece: The English translation. References to old Internet memes, such as Fawful's first line in the entire game being "[[AWinnerIsYou A WINNER IS YOU]]!" and the Fawfulcopter enemy being a reference to the ROFLcopter, date the English translation of the game to the late Noughties. TropesAreTools, however - Fawful's dialogue is incredibly memorable and serves him well in characterizing him as an extremely weird but still dangerous fellow.

** Not many people like the way you have to blow into the DS's mic in order to breathe fire during the Giant Bowser parts. This is especially frustrating in the battle against the Fawful Express, as this is the only attack you can do to hurt it since the train is too low to punch. The remake doesn't use the microphone on the 3DS, as it uses the touch screen for the attack now.
