Xbox v Polar.

Xbox or Playstation should team up with Polar to make controllers that check you heart rate, sweat levels, adrenalin etc.

Then as you play games they change according to how excited, relaxed, enthralled you are.

Imagine! Rather than your controller rumbling when your character gets knackered, you getting knackered makes it rumble.

All this data then gets uploaded so you get an overview of how excited/thrilled/tense the world is right now.

Then, all the date feeds a global chart of the most exciting game to play or the number 1 game for fear, etc etc.

I know you can get this for Wii already, but Wii ain't for the serious gamer.

Let's make it!
