I voted other. I like to play dance dance revolution, but I don't really consider it a workout (although I know others do and it can certainly make you break a sweat)
I've tried a few workout videogames on the Wii and I didn't really like them as much as DDR. The only one I liked was My fitness coach because it was more like a workout dvd that you follow along with than one that uses a balance board or motion detection.
I'm glad people like using them but I haven't liked most of the exercise videogames I've played. I'd rather just do an exercise video if I'm working out at home honestly
