Summary: Might as well buy a video. Uses very little of the system. Pretty much a computer generated video. Exercise are good. The tracker is wanting. For price thought it not worth the buy. Find something else. Doesn't even use the controllers. Voice gets annoying. And it doesn't even match what you are doing. So pretty much doesn't use any of the technology of the system. Way over priced. If it was $5 it would be an OK price. Never use it. Worthless program.
