A handful of developers have released some holiday-themed artwork before they shut down their offices for the weekend, so I thought I'd share the pieces we've received. The Witcher 2 holiday card features a full cast of characters from the game and the text "Best non-linear wishes from the makers of the best non-linear RPG!", while the Diablo III holiday card gives us a Santa-ized barbarian and the World of Warcraft holiday card shows off the team's cartoonish side.
