I think Wii Fit should fall under the mini-game category. That's all it is. Do this for 2 minutes, that for 3 minutes, etc. Not much else to do. Yoga isn't a sport. Dance Steps isn't a sport. Hula Hoops catching isn't a sport. I don't know what the heck that bubble thing is, but I know that isn't a sport. The only sport related thing in Wii Fit is the boxing training and maybe the jogging.
There is no mini-game catefory, and it surely isn't a party title.
Those activities are closer to sports than anything else ;)
