Wendi- I've had that happen to me before! So I bought the rechargeable battery pack, but after a little while of having that, it stopped charging! That was annoying. It still won't charge, but it comes with the cord that just plugs into the back of the Wii console, so I just plug it in and don't waste any batteries. Also don't have to worry about it dying on me!
Jessica- My favorite non-board game is Gold's Cardio Gym. I LOVE it. It has some activities you can do with the board if you want to (I never use any of it. It's just extra stuff they added in.) , but all the cardio boxing is just two Wii remotes. Great workout & fun!
