Psychonauts

Set in the fictional Whispering Rock Psychic Summer Camp, a remote US government training facility under the guise of a children's summer camp, Psychonauts follows the player-character Razputin (Raz), a young boy gifted with psychic abilities. As the player progresses, Raz picks up more and more psycho-talents and uses them to explore more and more of the camp. The game received amazing reviews, with particular commendation given for the game's art and level design. It might not have done so well financially, but with awards for best game and best screenplay, this is an undeniable masterpiece.
