With the Wheel, the Zapper, the Balance Board, and soon-to-be-released MotionPlus on the Wii (not to mention innumerable third-party peripherals), the thought of another add-on makes me balk.

But another device is exactly what Nintendo plans to release.

Nintendo President and CEO Satoru Iwata announced the Wii Vitality Sensor at the company’s E3 press conference, a device that measures a person’s pulse and will somehow help in relieving stress.

Not much else information was shared, but I think the general consensus was the same: not interested. Who needs to dedicate more space, and more money, to another piece of plastic?

And it’s not only Nintendo who’s guilty of this. DDR plants a dance mat in the room. Rock Band and Guitar Hero take up space with plastic instruments. DJ Hero will add a plastic turntable. Tony Hawk: Ride brings with it a skateboard peripheral. Sony already has the Eye Toy, but plans to release a motion-sensing wand to go along with it as well. Microsoft’s Project Natal is a while away, but will still vie for that precious TV-top space that the Wii Sensor Bar currently occupies in many households.

It doesn’t stop there, either. The list goes on in a tangled mess of plastic, wires, and dongles that makes my head spin.

Developers understandably want to immerse the player in their games, but it’s starting to get ridiculous.

I think I share the sentiment of many gamers when I cry: Enough with the peripherals!
