How long and hard is each God of War?

[elazz]

In all the GoW there are some difficult parts but I remember that I found GoW 2 the most difficult though that was on PS2 long ago. In God of war Ascension I did experience the most difficult part in any GoW game ever. It was the Trial of Archimedes but I think they patched that part with more checkpoints. Still a hard challenge. Boss battles are never difficult unless you play it on the hardest difficulty. Hades was just a pain in the ass for me.
