Psychonauts is one of the most brilliant games of the past decade. I am generally stingy with my compliments, but this here is UTTER BRILLIANCE on many, many levels. The writing, the dialog, the art style(s), the humor, the puzzles, everything is so remarkably well done that I was completely blown away. The only iffy part is the controls, but you get used to them fast.
If you haven't played it - go and buy it. Right this instant. The price is a mere $10, and believe me, it is easily worth $50.
For those of you who follow the gaming press, it is one of the very few games that Yahtzee (of Zero Punctuation) has spoken highly of.
I am extremely glad to add it under number 148 to the list of games that I beat!
