Did you buy a copy of Stalker or Mount & Blade War Band when they came out? Are you sick and tired of the DRM? Well I've got some great news if you fall into that rather specific category!
Gog.com has announced that you can input retail keys for select games and receive a Gog.com DRM free version. Join us past the break for details.
The deal only covers certain versions, languages, etc so you'll have to check out the details on the site to see if you qualify. Alternately you could just input the serial number and see if it works. Right now the deal is only with select games (listing below) but they plan to roll it out to as many games as possible in the future.
S.T.A.L.K.E.R: Shadow of Chernobyl, Call of Pripyat, Clear Sky
Mount & Blade: Warband, With Fire & Sword
This is a very small start, but if it works and they are able to expand this list then everybody wins. Gamers especially.
