Insanity effects using the gamepad and it's speakers could take the game to a whole new level of WTF.
Just after a tough battle, you're wandering down a dark lonely hallway and your sanity is running low, random things are happening up on the TV (like bleeding walls, enemies appearing and disappearing just as quickly as they appeared), and then the Gamepad goes dark like it shut off.
"pssst... pssst... down here" comes from the direction of the gamepad.
You look down at the gamepad, and a live feed of you looking at the gamepad shows up on the TV, you quickly look back up at the TV, and the screen changes back to the game and now you are on the gamepad screen but only for a few seconds before it flickers and puts the menu back.
------
they could use the mic to randomly record you saying stuff while you play and playback those recordings over the TV speakers during moments of low sanity.
gamepad could flicker and switch to one of the random VC games or apps you have installed on your system, only to cut back to the game moments later.
Main game character screaming for help in the gamepad screen and banging on the glass from the other side of the screen.

So much potential.
WTF is Nintendo doing with all their resources and IP's?
They need to redo this game and the ghost First person one too.
