7. Dr. Loboto (Psychonauts)
Summer camp can be brutal what with all the sunburns, mosquito bites, and brain thefts going on. Dr. Loboto has been absconding with the gray matter of the various children and counselors of Whispering Rock Psychic Summer Camp, and Raz is the only one perceptive enough to figure out what's going on.
After spending most of the game learning mind-bending super-moves and terrorizing the psyche of giant fish, you finally end up in Dr. Loboto's lair, ready to rescue your imprisoned friends. Instead of some twisted boss battle, Raz simply solves a couple of puzzles and activates a laser, launching Dr. Loboto out of his tower and sending him plummeting to his demise. Uh, victory, I guess? Then why do I feel so hollow inside?
