1. Psychonauts
No game exhibits as much magnetic appeal as Psychonauts. The brainchild of Tim Schafer and the crew of Double Fine, Psychonauts is a rare game that manages to fuse a compelling story with gameplay that I can only describe as being "very, very good" in the utmost sense.
It is a weird, and immensely playable game that places you in the role of Raz, a psychonaut in training who quite literally delves into the minds of others. Much of the game takes place in the Whispering Rock Psychic Summer Camp, and within the heads of the faculty and their students.
While Psychonauts may lack the 'epic' scope of Ocarina of Time, it makes up for it with its originality, writing, characters, art, puzzles, level design, and story. And as far as I'm concerned, Psychonauts is a grade above most games, regardless of genre.
