CCP has said The Witcher 2 on GOG.com has moved 35,000 digital copies, coming in second to Steam's 195,000 digital units.
All other digital outlets selling around 10,000 units each bringing the game's total to around the 250,000 digital units total for the May 17 - October 30 period.
"The digital sales of The Witcher 2 have exceeded our expectations," CD Projekt boss Marcin Iwiński told Eurogamer. "We are even more pleased that our own platform GOG.com had such a great share in the Witcher's success.
"The performance of GOG.com in selling new titles is not completely surprising, as we have said for years that DRM isn't necessary. It is gratifying to see that the only platform that offered The Witcher 2 DRM-free from launch has performed so well. "
As of the end of August, The Witcher 2 has moved close to 1 million units.
For those counting, the word digital was used six times in this post.
