- Acclaimed Flop: Paper Jam got decent reviews and fan reception, if fairly weak compared to previous Mario & Luigi games. However, the game ended up selling under 1 million units, a very low number for a Mario title.
- What Could Have Been:
- Running was originally going to be activated by pressing the A, B and Y Buttons in rhythm. Thankfully, Shigeru Miyamoto told AlphaDream to simplify it.
- Paper Luigi was supposed to be a playable character, but the developers didn't include him, as they thought having to control 4 buttons when commanding 4 brothers would be too frustrating to the players.
- Original characters were scrapped altogether as there were too many paper doubles of mainline characters running around, allowing for ideas involving contrasts.
