We got the Wii about 6 months ago. I believe it can still be hard to find. My sister bought her kids one and called me asking if I wanted her to get another one for us. We had not been able to find any in the stores.
My husband was more excited about playing this than my son was. We love the Wii. We had so much fun creating our Mii characters to play with. Everytime someone visits, we create them a Mii and play together. I love the way that the system recognizes the controller movement with your hand. My only complaint is that sometimes I am unable to control my movements on the system and have not figured out how to adjust it so that it does not move so fast. Maybe it is just me.
My in-laws are in their sixties and they have just as much fun with this Wii as we do. It is definitely a family game system and a game system for all ages.
