Given the messed-up things they managed to pull out of the GameCube, I shudder to think what these guys could pull off with the power off the Wii Remote.
You're walking through a dark, foreboding chamber. You examine the pristine oil paintings of a magic ritual gone wrong, trembling as you walk. A door slams open, and a large group of bloodthirsty monks swarm in and knock you down. As they crowd over you, You punch and swat with the Wii Remote and Nunchuk, desperately, futilely trying to bat them away. You hit the list one, get up, and shoot them all down. As the last one falls, he disappears in a flash, and as you realize that nothing was there, your sanity level drops down to nothing...
*shudders with glee
Also, if Nintendo owns the sanity meter couldn't they make a case against Quantic Dream for the depression meter in Indigo Prophecy?
