It was fine for The Walking Dead, but I tried it for Infamous and it wasn't really playable. i would play the first two because the build up is what made god of war 3 amazing in my opinion. Yes,but you'll be cheating yourself. Yes, and no. Hope that helps.
God of war 1 (2005) God of war 2 (2007) God of war betrayal (2007. Also not on ps now but doesn’t impact story too much) God of war: Chains of Olympus (2008) God of war 3 (2010) God of War Ghost of Sparta (2010) God of War Ascension (2013) Now if you would like to play in story order this is the chronological order.
There is a 20 minute YouTube video on god of war 1 2 3, if you want to not play the games and still enjoy this title I would search this one. I have played and beat every title except for Acension, and Ghost of Sparta, yet my wife hasn't.
