Paul Richards is putting together a very interesting book called Substrata.
The Pitch : When Vigil Games dissolved shortly after the release of The Art of Darksiders II, I thought "What a shame that the contributing developers [now scattered to the four winds] will never appear in the same volume again." Then I thought, "Eff that! We have The Internet. We don't need to be working at the same company to make an awesome, game-styled art book."

Wish I had saw this sooner myself!
