We have the Wii with Wii Fit board. We use it mostly during the winter time when our kids are indoors more than outdoors. Summer time it sits unused unless a friend stops over.

I like the games that are more active like sports and party games. This allows the kids to move and interact with each other. DS5 did get SuperMario for Christmas and we have played that as a family. DD11 loves a game where she is on a safari and has to take pictures of animals and plants, but I am not sure of the name. Another fun game for our family has been guitar hero and we can play together at different levels. Added bonus is that DD11 has been introduced to the music DH and I used to listen to. "Eye of the Tiger" is her favorite.

For DS5 Wii has been an earned reward instead of something he is allowed to play every day.
