Toroid Terror was my favorite year. Having to find a way to manipulate a tube and change its orientation to score was very interesting. Also having to pick out the proper color to score. I personally liked all the games when the scoring objects were Red, White, or Blue based on which station you had. It made the field have a look that you don't see anymore. Also 1997 was the second year of Rumble at the Rock and that competition was just awesome.
