I can see where a cottage industry could crop up making different peripheral controllers, like a flight stick for flying games or a pistol for "Time Crisis" (PS1, PS2) shooting. How about a knife to cut people's throats in games (ala Turok (1) on the N64.) Actually, just the movement could be emulated with the present controller. We'll have to see how well the mechanics are implemented in the next Prince of Persia game for the Wii. I just hope that distributors don't start making many games on rails where you are manning a turret.
