The acclaimed action-platformer Psychonauts bears all the marks of a mad Tim Schafer/Double Fine creation: a zany premise, standout characters, and fun-above-all gameplay. In Psychonauts, you play as Raz, a psychically gifted kid at a summer camp-slash-training facility for mentalist super agents. When the camp falls to a dastardly deception, it's up to Raz to traverse through the minds of various camp characters to save himself and his friends.
