Super Mario 64 2

Super Mario 64 2 is a cancelled sequel to Super Mario 64 that would have been on the Nintendo 64DD and released on May 1st, 1999. It was cancelled due to the DD's commercial failure, and lack of progress on the game, only having a single demo level that was not revealed to the public. It also shared a codename with Super Mario 128.

This game would have had a playable Luigi in a multiplayer mode, as well as a rideable Yoshi. These features would go on to be used later in the Super Mario Bros. series. It is unclear if the game would have had the Personalization A.I., though it is possible.

Some believe this game would have been the similarly cancelled Super Mario 64DD, instead of the game being a direct port of Super Mario 64 to the 64DD. Some say that the game went on to become Super Mario 64 DS, while others simply say it is the closest we will get to Super Mario 64 2.
