With motion-sensitive gaming having largely held the center-stage at the recently-concluded Electronic Entertainment Expo (E3), the three gaming console bigwigs - Nintendo, Microsoft, and Sony - are apparently vying for the top slot in the motion-controller space.

While the Nintendo Wii has been ruling the roost for the last three years, Microsoft is readying its Kinect motion-controlling device, and Sony is coming up with its PlayStation Move. All of the three devices have their respective pros and cons.

The 2006-released Nintendo Wii - which comes packaged with a Wii remote and analog-based Nunchuk controller - is a fairly easy-to-use device which largely utilizes motions based on player movements, to establish interaction with on-screen characters. Though the $200-priced Wii is a good buy, its main disadvantage is a large chunk of lackluster games.

In comparison, the Microsoft Kinect a sleekly designed motion bar that plugs into the Xbox 360 console; and monitors the gamers' bodily movements to play a video game without holding onto anything! While the Kinect boasts a cool and futuristic touch-based menu system, its $150 price-tag is apparently too steep for a standalone gaming device.

Lastly, the Sony Move controller, featuring a glowing ping-pong-ball-attachment at one end, reads the motions of the gamers via the camera and carries out actions on-screen. However, the $50-priced motion controller additionally requires a $40-priced secondary navigation controller, the PS3 system, the PS3 Eye, and the proper software to read whatever gamers are doing!
