Nintendo Wii is probably the best game console ever created! Not only for the new and improved "wii"mote that adds hours of interactive gameplay, but also for the re-designed way that you play your games. Interactivity is the new black!!!
I was quite dissapointed with some of the games though. From my first experiences, you need to try it before you buy it. Otherwise, you will end up spending money on games that will collect dust on your TV stand. I learned that lesson with "Super Mario Galaxy".
My major dissapointment was the price of the console and what package it included. Too pricey for too little. Only one remote??? Come on, Nintendo. I have seen senior citizens play bowling in groups. You need at least two. One word of advice, buy Wii bundle. It ends up being cheaper that way.
Overall, though, Wii will certainly add hours of fun to your family entertainment, make you lose a few pounds, and keep you inside the house for hours at a time (just kidding).
