9. MadWorld
On the one hand, MadWorld's cartoony style and black and white graphics disguise its hyperviolent streak, but on the other, they make it just that more shocking, as every bit of blood you spill stands out that much more. The game also wins points for getting away with all this on the Wii, as Nintendo has gone to great lengths to ensure that their console has a family friendly image.
MadWorld may not be the best of games, but it's certainly one of the goriest experiences the Wii has to offer. It's amazing that Nintendo allowed this one to pass.
