pros:
Ultra Violent, you can cut of other peoples limbs and see the blood fly in all directions, Cool.
Sword fighting! Man would I love to do that in real life :(
Cons:
Controls, controls, and... controls. TERRIBLE!
conclusion:
definitely buy it, it's a GREAT game, lots of blood and actions, and cool weapons, but the controls aren't too handy. You'll get used to them, tough :)
