Despite being one of the most popular games ever to be released, Super Mario 64 never got a sequel. Super Mario 64 is arguably the most ground-breaking Mario game in the franchise so it's always been surprising that it wasn't directly followed up. Not only does it set the standard for 3D gameplay, but it introduces many Mario concepts we know and love. Perhaps most importantly, the DS version was the first to make characters other than Mario playable (Yoshi, Luigi and Wario).
But a sequel was actually planned for Super Mario 64 – it even had a name. So what happened to Nintendo's 'lost' sibling to one of its most popular games?
