Question: How many total games are there included in the God of War franchise? Passage:As with previous games in the God of War franchise, God of War: Ghost of Sparta is set in an alternate version of ancient Greece populated by the Olympian Gods, Titans, and other beings from Greek mythology. With the exception of flashbacks, the events are set between the games God of War (2005) and (2007). Several locations are explored, including the fictional city of Atlantis (and later a sunken version). Atlantis is a mythical city erected by the Sea God Poseidon, and houses the Temple of Poseidon. Near the city is a real-world location, the Methana Volcano, which is contained by the archimedean screws and is also the prison of the Titan Thera, who is guarded by automatons. On the outskirts of the city is the Temple of the god Thanatos, the location of Death's Gate and portal to the Domain of Death. Other locations include the Island of Crete and its capital city, Heraklion, the Mounts of Aroania, the ancient city of Sparta (also home to the Temple of Ares), the Mounts of Laconia, and a brief scene above the city of Athens featuring Suicide Bluffs, the highest cliff in the city overlooking the Aegean Sea and a recurring location during Kratos' adventures.
