The biggest complaint among today's console and PC gamers? Well, if some peripheral manufacturers are to be believed, it's their inability to experience actual physical damage. A while back, we told you about TN Games, which manufactures a vest that delivers blows to your sternum in sync with the game that you're playing. The company has subsequently developed a helmet that does the same for head blows.

I had the opportunity to test both out at this year's CES, and I have the video evidence to prove it. I'm not a huge gamer, so I think I can safely say that I'm not going to rush out to purchase either. But again, that's just me.

So what's the next step in video game-inflicted pain generation? If you guessed electric muscle stimulation technology, you're correct! A company called Mindwire Limited has harnessed a technology created for muscle-toning therapies, using it for the noblest cause of all: helping people hurt themselves while playing video games.
