Bringing forward all of what made Wii Fit so great in the first place, then adding new features and the Wii Fit Meter means that Wii Fit U is an excellent package designed to get friends and family playing games while getting fitter. How can that be a bad thing? It can be a bit pricey if you don't already own some of the hardware (Wii U, Balance Board), but this is an example of something succeeding in exactly what it sets out to do, and sometimes that's enough. Bare in mind, however, this is not a full substitute for a real exercise routine and gym workout.
Legends is still a wonderful game, and the tight controls work incredibly well on the Vita – I am particularly fond of the sticks. With the challenge mode present and a good amount of content to get through (including the Back to Origins levels), this is still an excellent game, if ever so slightly inferior to the versions that have come before it.
