One of the funniest, most creative, and beautifully stylistic games ever made, "Psychonauts" centers on a boy named Raz who runs away from the circus to sneak into a summer camp for those with psychic powers. To progress in the game, you must jump into other characters' minds, gain new psychic abilities, fight their demons, tag their emotional baggage, and defeat their other mental afflictions.
