I loved lightgun games on the old systems, and I think the Sega Saturn's Stunner was the best hardware of the lot. The obsolescence of CRTs pretty much killed the tech, but the gameplay style has made a bit of a resurgence a couple times with the advent of the Wii and VR.
I have never even seen a foot pad controller, like for Track and Field or the more popular Dance Dance Revolution, for a PC. Actual car/plane pedals and shit, but not just a big flat controller you play with using your feet.
