GOG has been a synonym of classic PC gaming since it launched in 2008, with a library of cheap, DRM-free titles that's been growing steadily ever since. Today they have announced their biggest partnership yet, one that will bring Activision's wide array of back-catalogue games to their digital platform.

They are kicking off the deal with just two games priced at a mere $6 apiece – Arcanum: Of Steamworks and Magick Obscura and Gabriel Knight: Sins of the Fathers. The first a steam punk-esque RPG in the style of the classic "Fallout" games, while the latter is a voice-acted revamp of Sierra's 1993 adventure game. Further Activision titles are due to be added each week during February.

In related news, Marcin Iwinski, Co-Founder of GOG.com and its parent company CD Project, was recently interviewed by GameZebo and let slip one interesting tidbit: iPad compatibility might be in the works. Though not officially confirming anything, Iwinski shared a Photoshop mockup depicting an "Apple Multi-Touch Interface"-compatible version of Adventure Soft's Simon the Sorcerer. Guess that sort of answers the question we made them a while ago regarding their plans on the mobile space.
