Super Mario Bros.
That game where you are a plumber who can jump over 30 feet in the air, and use sewage pipes as transportation. You also crush brown mushroom things, and kill giant turtles for their shells so you can attack more of these creatures so you can save a princess who does not have a king and talk to walking mushrooms.
not very sick and twisted
kirby 64 (the crystal shards):
you are a corrupt pink fluffball that eats creatures and kills off creatures with the essence of others
you battle a possessed friend and save him, the two of you go on further
you battle another possessed friend, an artist that can create paintings that live and breathe; paintings that you must kill as well.
you battle yet another possessed friend, apparently this time a penguin-like creature, to show the innocence of your friends that are possessed.
you then kill a creature leader, and blast it in the eye with whatever you fire as it bleeds.
the creature has wings and a halo.. and grows a cactus on it's bottom.
you can rip off it's wings and torture it to slow it down.
perhaps your friends were possessed as revenge for something?
because you certainly are cruel
