So I was thinking of a game I'd love to see them make for the Wii:
A gladiator game in which the wimote and nunchuck are primary and secondary (or shield) hand weapons. And the weapon will mimick EXACTLY what the remote does. I'd love to see them get the physics down just right so the damage and strength factors are infinite and depend purely on how you swing the controllers and what it contacts.
Since the game would take place in an arena, the necessity to move around becomes minimal which will allow the controls to focus mainly on your swings, blocks, whatever you do with the controllers. Movement can be minimal & would be determined if the wii can sense your movements slightly left, right, back forward, duck and jump due to the controllers.
What might be neat also, is if you swing or try to deflect and you have significantly less power on it than your foe, the weapon will be knocked out of your hands if you do not compensate quickly to swing your weapon or shield away due to the force.
What do you guys think? I don't have a wii yet so I'm not even sure if this is possible with the system.
