Mario's Time Machine (NES)

Mario's Time Machine is an educational platformer originally released for MS-DOS and then for the NES and SNES. The Software Toolworks both developed and published the MS-DOS and Super NES versions in 1993, while the NES version was developed by Radical Entertainment and published by Nintendo in 1994. The MS-DOS version was re-released as Mario's Time Machine Deluxe in 1996.

Mario's Time Machine is one of several educational Mario video games that were released during the early 1990s; the game focuses on teaching human history. While the gameplay and engine varies between the three different versions, the story is roughly the same: the player assumes the role of Mario, who uses a time machine to return various artifacts, which had been stolen by Bowser, to their correct points in time.
