Query: An Underrated Classic

Psychonauts is one of the funniest, most imaginative and well written platformers ever made. All the levels in the game look gorgeous and the level design is simply amazing (genius even, on a few levels). The characters in the game are all unique and interesting, which makes for a very entertainging and engrossing story. Its a real shame Psychonauts didn't sell very well when it came out because this is a game that everyone should experience.
