The games have never been played. I bought them and then put them on the hard drive. I have about 50-60 games. The kids love it and its very interactive for them. $25 each or $150 if you take them all?
What are Wiis like as an exercise tool? Can you get a really good workout on them? The exercise in the ads looks a bit tame, but if you're restricted for better ways to get active then they could go alright I reckon.
