Psychonauts

If you grew up hooked on quirky, funny Lucas Arts adventure games like Monkey Island, Maniac Mansion/Day of the Tentacle, and so on, this game is for you. You might not realize it, since it's disguised as an action-packed 3D platformer, but this game has the heart of any of those greats. You spend as much time exploring, talking and finding/using items as you do smashing and burning things with your awesome psychic powers. The dialogue is hilarious, the voice acting is superb (anyone notice that Raz is actually Zim, from Invader Zim?), and there are plenty of funny gems to be found by those who think creatively enough to find them (light a squirrel on fire for some funny lines from Raz, for example). The only problem is the action and difficulty level is a bit inconsistent throughout: some levels are excruciatingly difficult and some are a breeze, in no particular order. However, the overall fun and vision of the game is more than enough to keep you pressing through the more frustrating moments. Definitely a must-play.
