In the many years since its release, many creative, technically-minded fans have used this classic title as a foundation to craft their own mods and fan games, spawning even more ambitious projects inspired by the original Mario 64.

Take the dynamic, solid gameplay of 3D Mario and mesh it with Sonic's adrenaline-fueled speed, and the result might be this project by ROM hacker Thodds. This one also runs with the core foundation of the original game, for the most part, keeping most of the classic level design and assets while swapping out the music, sound effects, and various enemies.

Still, the added quickness of Sega's blue hedgehog, who can use his spin dash as well as homing attack, and even run on water, gives this the vibe of a (rare) great Sonic 3D game; just one in the Mario universe. Snag this heart-pumping fan game here.

4 Super Mario 64: The Missing Stars
