Today, something different for you:
The Witcher Goodies Collection will be free at GOG for the next 44 hours. To get it, just go to gog.com, scoll down a little until you come across the giveaway banner and click the big green "Get It Free" button. The goodies will show up in your library a moment later.
This collection contains artbooks, soundtracks, wallpapers, making off videos, concert videos, and other such stuff, drawn from The Witcher franchise. Mind you that it does NOT contain any of the actual games.
Have a look if interested and enjoy.
