Six games harder than Ninja Gaiden Sigma 2

Remember, thumb blisters drive the ladies wild. We hope.

1.
Ecco the Dolphin - Genesis
Life in the deep blue ocean is touch for Ecco.
2.
Monster Hunter Freedom 2 - PSP
No HP Meter, difficult combat and huge monsters. Oy.
3.
Punch-Out!! - Wii
Think you beat the game? You haven't even gotten started.
4.
Mega Man 9 - Wii
Tae Kim's the old in old-school, and even he can't beat it.
5.
Devil May Cry 3: Dante's Awakening (Special Edition) - PS2
Lose too much, and the game will unlock Easy mode. Ouch.
6.
Ninja Gaiden: BLACK - Xbox
Of course, the demons are less dangerous than the ninjas.
