My favorite games are the Witcher 2, Mount and Blade Warband, Crysis, Battlefield 3, Dark Messiah of Might and Magic and Dragon Age: Origins. Most of my time that I spend on the computer is on Steam which is where most of the games I own are but I found Desura and might spend some money here as well sometime in the future :)
These are some Fallen Earth wallpapers I have that I downloaded when I was addicted the game. (which I still am) :D (I did not create the images you can find them at Gamersfirst.com)
