God of War III's game director, Stig Asmussen has said that the series' former directors disagreed about how the story would end and Kratos' direction in general.
Talking to GamePro, Asmussen said, "What David Jaffe talked about doing was basically, you destroy Greek mythology and then Norse mythology is right around the corner."
"It becomes clear at the end that he's going to become this harbinger of death across different mythologies in the world and maybe carry the series on from there."
"Cory Barlog talked about Kratos becoming Death. He pretty much becomes the Grim Reaper at the end of the game and his blades become sickles."
Asmussen goes on to say that he thought both ideas would have worked but he didn't use them simply because they weren't his own:
"They're both incredibly good ideas, but you need a director to be passionate about the story and understand it intimately. If I had used Dave or Cory's idea, I wouldn't have been as passionate about it."
