Super Mario Maker and its sequel are terrific games that let fans create and share their own Mario levels with ease. But it was a bit of a disappointment that Nintendo only factored in the 2D Mario games. None of the plumber's 3D incarnations have made it to a Mario Maker title to date. So thank goodness for modders.

A pair of modders named Arthurtilly and Rovertronic have released an open-source Super Mario 64 mod that aims to make it a cinch for players to create and share their own levels. You'll need your own (legally obtained) Mario 64 game file and a separate piece of software to infuse the mod into it. It's even possible to use Mario Builder 64 on a Nintendo 64 if you have a supported flashcart.
