Super Mario 64 2

Super Mario 64 2 was the tentative title for a Mario game in development that was going to be the direct sequel to Super Mario 64, intended for release in 1999. It was going to be for the Nintendo 64DD, but was cancelled early in production due to lack of progress and the commercial failure of the 64DD add-on. Only one demo level was ever made but was never publicly revealed. It is possible that some concepts of this game were included in Super Mario 64 DS. It is also possible that Super Mario Sunshine, Super Mario Galaxy, or Super Mario Galaxy 2 could have elements salvaged from the development of Super Mario 64 2, according to Nintendo during an E3 event. Had it been released then this would have be the first time a 3D Mario platformer would have received a direct sequel, predating Super Mario Galaxy 2.

Luigi was also set to appear in this game. It can be assumed that he would have been playable, as Shigeru Miyamoto had planned to make Super Mario 64 2 multiplayer – in fact, the first playable demo level was multiplayer. Miyamoto also had stated (while still in the process of making the game) that he was thinking of releasing the game on an entirely new gaming system. It is also unknown what Power-Ups, if any, were going to appear in the game.

While it is cancelled, some people believe that it is the prototype disk "Super Mario 64 Disk Version."
