Super Mario 64 2

Super Mario 64 2 is a tentative title to cancelled sequel to Super Mario 64. It was set to feature Luigi as a playable character in the game's multiplayer mode, and had a mountable Yoshi. Originally planned for the Nintendo 64DD, it was cancelled when the console proved unsuccessful commercially. While scrapped, ideas from the game live on with future Mario installments such as Yoshi being introduced as a rideable companion in Super Mario Sunshine and Super Mario Galaxy 2.
