Most difficult moment in gaming?
Ninja Gaiden Black. Mission mode. Master Ninja difficulty. Fighting Nicchae and Ishtaros together. You needed the zen calmness of a Buddhist monk (to avoid controller genocide), the mental dexterity of a Math Olympian (for the advanced 3D modeling you needed to do in your head to predict how to avoid the incoming attacks of two relentlessly lethal and agile, yet tactically independent adversaries) and the reaction speed of a housefly (to implement said strategies) to beat this challenge.
