all god of war moments...
God of War 1 the 10 trials...when you screw up you start back at challenge one...that 8th challenge made me its bitch
God of War III: the Cerberus and those jackal-like enemies(my first play-through was on hard)
and God of War Ascension: that whole trail part(before the patch)
only times where I was livid enough that I was yelling at my TV
EDIT: Also Vanquish: challenges 4&6...the only thing preventing me from platting it
