If you don't know who Tim Schafer is, you're doing yourself a disservice, but just in case here's a short back story. Mr. Schafer is the gaming genius that brought us The Secret of Monkey Island, Day of the Tentacle, Full Throttle, and Grim Fandango when he was working for LucasArts and they were pumping out the best point-and-click adventure games money could buy. In 2000, Schafer left LucasArts and started his own company, Double Fine Productions. Their first title, Psychonauts, is probably one of the most unsung pieces of genius in the gaming world, as there were some distribution and marketing issues when the game launched in 2005. Because of the cult-ish success the game has seen since its release, Double Fine has created Psychopedia; a Wikipedia for the world of Psychonauts. Hit the Read More link for hilarity and self promotion.
Psychopedia has everything a fan could want; full profiles for every camper, staffer, and character that made us lol in the oh-so-brilliant platformer. Everything is listed and catalogued alphabetically, from the enemies you fight to the items you collect. My personal favorite is the section where they detail all the "Mental Worlds" in the game, which are just as inspired, beautiful, and hilarious when we saw them for the first time. But of course, the best thing about the site is that G4 is featured on the front page. Back when the game came out we asked Double Fine to make us some bumpers using the cast of Psychonauts, and they have posted those bumpers as their featured article. Nice. Check out the site at doublefine.com/news.php/Psycho-pedia for everything I already mentioned plus videos, cheats, credits, and some extras for the hardcore fans. And if you haven't played the game before, do yourself a huge favor and follow the links on the front page so you can order yourself a copy. You'll thank me later.
