That achievement belongs to the God of War HD Collection.Sony has confirmed that the HD remastered port of the first two God of War titles initially released on the PS2 has sold a million copies since its 2009/2010 debut.
Ported to the PS3 by Bluepoint Games the God of War HD Collection featured high-definition resolutions (720p), anti-aliased graphics locked in at 60 frames per second, trophies and more. Early copies of the collection also included a playable demo of God of War III.
