I just realized something.
All the God of War games except one were released in March. The modern word
March derived from Martius, the first month of the Roman year. The word
Martius is derived from the word
Mars and meanss "Month of Mars".
Mars is the Roman name for the Greek god of war
Ares, the first antagonist of the God of War games. Therefore, all but one of the God of War games were released in the
Month of Ares!
