I have been waiting for someone to come out with workout focused video games ever since I left the arcade sweating after playing an interactive mountain biking game. The game was competitive, fun and a great workout....but it cost me a few bucks for each race. If games of the future were centered around fitness the geeks of the world might start bullying people at school instead!! Ok, that is a stretch but this would be great for our obese country. Imagine jumping on your treadmill or stationary bike and racing people around the world! I think it would be a blast!
Nintendo and has begun to entertain this idea with Wii Fit. Right now it only looks like you can workout with this balancing pad by doing yoga and other exercises but hopefully soon there will be other interactive devices
