I am a obese late 30's male. We had a game as a Birthday party for our 10 year old son. I played just to keep an eye on the kids but within minutes it had its claws into me. The other parents were shocked to see me break out of a walk for the first time in over a decade. Tomorrow will be my third game in six months of my first experience. Really is fun for the whole family. (Date of experience: Nov, 2009 )
