Nintendo promised a revolution with the Wii and there's no doubt that it's opened many doors for videogames. Firstly in terms of the new types of play possible and also, thanks to the massive and varied audience the Wii now commands, in the types of product which can be seen as commercially viable in the new, broader, games market. Yoga is one such product. It isn't a game as such, there are no challenges, no rewards and no scores; it is designed as a virtual yoga retreat giving you full access to all the disk's content from the start.
