Gore, blood, and dismembered bodies probably aren't the first things that come to mind when you think about the best Wii games around. But then again, MadWorld is pretty much five miles out in left field when compared to the rest of this lineup. Touted as a rare M-rated title for the Nintendo Wii, MadWorld put you in a "Kill or Be Killed" world that delivered deliciously dark ways to murder, maim, and mash the living Hell out of anyone who gets in your way. By far, some of our favorite moments include the "Bloodbath Challenges," like Rocket Reamer and Man Golf. Oh, and stepping up the difficulty just makes the game even better, so don't wuss out.
