No. 8 The Witcher 2: Assassins of Kings
Copies sold: 2.2 Million
Year of release: 2011
The sequel to The Witcher, The Witcher 2: Assassins of Kings, was released three years ago with enhanced combat systems, more complexity, and several mini-games within the main story. Yet, it seems some players had issues with the video card compatibility, and the game presented various support issues which hurt its popularity. Nevertheless, it remains a huge success and slightly outdid its predecessor.
