Wii Fit not only lets users try a variety of exercises of ever increasing intensity, the game also charts progress. This way, users can also see how far they've come over time and even record physical activities they've done outside of Wii Fit. It's worth noting that, because of the structure of Wii Fit and its own uniqueness, many enthusiast reviewers had difficulty assigning a quantifiable score to the product; sure, much of the game is reliant upon repetitive activities, but so are most workout regimens, and like any workout regimen, you get out of Wii Fit what you put into it.

"With the tracking feature, users can see how they and their household members improve with time," commented Kaigler. "Like the gym, Wii Fit keeps you coming back for more. We saw consumers respond similarly to the Brain Age games, which also let you track your progress. There's nothing like seeing your positive results tracked on a chart to make you want to continue."

Of course, Wii Fit also has a set of Balance Games for users to try. This set represents the most "game-like" elements in the whole package, where players use the Wii Balance Board to ski jump, head soccer balls, and walk a tight rope, among other activities. These mini-games no doubt appealed to consumers looking for a title like the other games in the so-called "Wii Series" that include Wii Sports and Wii Play.

"I'm sure the fun games and activities in both Wii Sports and Wii Play paved the way for people to enjoy those in Wii Fit," said Kaigler. "People like new challenges, and Wii Fit offers people a completely new way to interact with their games."

Potential in that little white thing you stand on
Despite reports of the "largest ever" ad campaign from Nintendo of America to support Wii Fit, such a campaign did not seem to materialize. It's as though the biggest promotion the game received was during E3 2007, where it was highlighted at Nintendo's press event and given a long promotional trailer that was humorously mocked on YouTube. Nintendo even offered no comment on the promotional campaign for this article, leaving us with a two-fold conclusion: one, Nintendo knew that Wii Fit would be popular anyway and two, they probably knew their initial shipment was going to come up far short of demand and felt there was no need to exacerbate that with an extensive ad campaign.

Wii Fit is most certainly a hit and just another case of Nintendo moving from strength to strength with its Wii console. Considering the success so far, we'd anticipate seeing another game in the popular "Wii Series" at E3 next week. The future is even brighter for the Wii Balance Board, with Namco Bandai, THQ, Ubisoft, EA, Activision, Majesco and Koei all planning on supporting the device, with others likely to follow.
