The first time I played the original God of War (no, not Dad of War, the original back on PS2) on the highest difficulty, I got all the way to the final stage of the fight with Ares, started the minigame grappling with him for the sword....and the game locked. But the audio was still playing, so I just had Kratos and Ares grunting at each other while everything else was stuck.

I still count it as a win, though.
