All that for $40!??! Holy crap, I wasn't sure I needed the PC version but I could probably sell the game and keep the rest without being out too much. Damn you THQ. Edited to add that the cheapest shipping is over $11. Ouch. If you add it to the cart, though, you can see pictures of the included stuff. The book is a hardcover manual with the symbol on front, the T-shirt is gray with the image of War on Ruin (and only XL), the pin looks kinda cool. Map is pretty colorful. I love Darksiders, so it's hard to resist this stuff.
I just read elsewhere that there's supposed to be a "Hellbook Edition" with a soundtrack and art book? Don't see it listed, though.
