Definatley Ninja Gaiden 2, i lost two controllers to that bitch. 1 to the first boss, with his homosexual eyepatch, and the other too where i barely beat a boss, survived for about another hour, died, and then sent me back to boss again. I tried again, and couldn't succeed. Brought the game back to Gamestop the next day.
QOTW: What's the angriest you've been at a game?
