"The first thing you'll notice upon wandering into the main hall of the Classic Gaming Expo? A series of TVs, set up with reproductions of both the 1990 Nintendo World Championships NES cart, as well as the lesser-known 1991 Nintendo Campus Challenge -- boy, college life seemed a whole lot tamer 20 years ago, didn't it? If you don't know about the former, the 1989 movie The Wizard -- which we'll be talking about on this week's Retronauts -- planted the idea in the brains of receptive children shortly before Nintendo rolled out their event nationwide (strangely enough, these "world" championships didn't stray outside of the continental United States). The Classic Gaming Expo features their own take on this fabled event, though it involves two different competitive carts, and the stakes are much lower -- no trip to Universal Studios (gasp!) for the winner of this one. Sorry, but you'll have to visit the smoldering ruins of the Back to the Future ride on your own dime.", writes 1Up.
