We know it's not strictly connected with The Witcher, but our sister site GOG.com, that offers DRM-free classic PC games, has just announced the addition of Activision games. The good news for us, RPG fans, is the release of one of the most diverse and open-ended RPG: Arcanum: Of Steamworks and Magick Obscura. Created by many of the same minds responsible for the Fallout series, the game places players in a refreshingly unique setting, as ogres and other fantastical creatures come to grips with life in the midst of an industrial revolution. The second release from Activision is the first part of point and click adventure games series Gabriel Knight: Sins of the Fathers. Both games are now available for $5.99 each, compatible with modern operating systems and DRM-free.
