7. Ninja Gaiden II
The Ninja Gaiden franchise is notorious for two things: its brutal difficulty, and its extremely bloody gameplay. Ninja Gaiden II is easily the worst offender in the series, as the power of the Xbox 360 paved the way for some fairly brutal combat, allowing you to slice and dice enemies into a pile of limbs and an unhappy torso.
Sadly, Ninja Gaiden II may have been Ryu's violent last hurrah. The PS3 rerelease, Ninja Gaiden Sigma II, had the gore toned down susbstantially, and the upcoming Ninja Gaiden III won't even allow you to dismember your enemies.
