Gameplay
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.
