Wii MotionPlus

Pros: 1:1 motion control, more natural feel to some games, ends the era of "wagglefest" games.

Cons: Only available on a few titles, Another accessory to buy for the Wii.

Summary: Contrary to the CNET reviewer, I would easily rate this product a buy, with one caveat. You have to really want the game that requires the MotionPlus. I bought the MotionPlus with Tiger Woods PGA Tour 10, and the gameplay of that title is greatly enhanced by the MotionPlus. More than adding simply Draw and Fade, it drastically overhauls and improves putting in the game. I have owned several copies of previous Tiger Woods titles and this title is the only one that accurately represents the joy AND anguish of golf.
The bottom line is that if "waggle" games and lack of true 1:1 motion contol have bothered you, or you really want a game that requires Wii MotionPlus, it is definitely worth the $20 investment ($10 if bundled with a game). If you just like to play casual games and don't need one of the titles that currently offers Wii MotionPlus support, wait until a game that you "have" to have before buying this accessory.
