My friend just let me borrow a copy of God of War 3 for the PS3. I finished God of War 1, God of War Chains of Olympus, and Ghost of Sparta, but I never played God of War 2 yet. I have God of War 2 though, but my friend lend me the god of war 3 for only 2 weeks. So should I just play the God of War 3 to finish it, or play God of War 2 and then buy God of War 3(Which I really don't want to do)... I am just scared I won't understand the story line.
