I second Shaq Fu, Revolution X, and The Rocketeer, but I defend Secret of Mana, Battletoads/Double Dragon, Buster Busts Loose, and Ranma 1/2. C'mon, people. The topic says "the worst," not "the mediocre." If the game does not inflict actual pain, it does not belong on the list.

And whoever mentioned Super Mario Kart, I charge with having bad taste. Veridct: guilty by reason of insanity.
