One of five Mario-related edutainment games for the super NES, Mario's Time Machine is the weakest of the bunch. As the title character, players travel through time, answer a variety of history questions, and return artifacts (which were stolen by Bowser) to their rightful owners. The action sequences, which involve gathering mushrooms while cruising the surface of the ocean on a mini-surfboard, are enemy-free and dreadfully dull.
