 At Comic-Con 2010, Jan noted that when development began in 2008, the goal was to make the game bigger than "Chains of Olympus", which had apparently pushed the PSP to its functional limits.Jan stated that "Ghost of Sparta" took the PSP to its "absolute capacity", with another feature being more on-screen foes.The game concept was originally used as a teaser for players who obtained the platinum trophy from "God of War III".
