skeletonbow: The Witcher is currently available for free on GOG, however it shows up in store with a price on it. You have to go directly to the game's page, then add it to your cart upon which time it shows up as FREE through checkout. Only one free copy per person.
Some people have reported that they do not seem to be able to get a free copy. Not clear if they're doing something wrong, or if it's not available to them. Also not clear why it is free to begin with and what promotion it is a part of or what the criterion is to get a free copy (if any).
If anyone knows why it is free and/or why it doesn't seem to be advertised anywhere, please add info about that below.
Gwent beta. I'm guessing you never redeemed your free copy...
