I do like the golf on Wii Sports but have heard Tiger Woods is a little more difficult. I guess it could help me learn to play a better round of golf though.
I was one of the suckers who stood outside Target on release night, first in line . 7:00 PM starting time. Super Smash Bros Brawl Mario Kart Wii Super Mario Galaxy Legend of Zelda - Twilight Princess Wii Play was decent, although Wii Sports is probably one of the best. Then of course you got the VC or if you have skills, you can easily do what people do on their PSPs.
I've seen a few people mention Zelda on here and I loved the latest one on the DS, might have to invest in that.
Mario Kart is the best on the Wii. If you setup wireless internet with your Wii you can connect to other people via a central Nintendo server and race/battle them online. It's awesome My wife is hooked on Wii Fit.
Invested in Zelda and Res Evil over the weekend for the Wii, both are fantastic games. Loving the look of the Zelda game so will probably be hooked for the foreseeable future.
