Exactly what's wrong with the score?

That is a really good score for something as unconventional as WiiFit.

Yeah reviewing a "game" like this is incredibly hard. I mean, how are you supposed to rate it? There's nothing to compare it against, really. Yeah, there's Wii Sports, but that's not the same. And obviously graphics and sound hardly matter in WiiFit. Soooo... hard, yes. :p
All in all I must say that I'm actually surprised by the score. I was kind of expecting them to give it a lower score.

People seem to expect 9s and 10s for every hyped game released. Its unrealistic to think that everything will. 8 is a really good score and people should be happy with it. I've been saying for years that games aren't judged harshly enough.

The BMI is perfectly fine for adults, and is almost never a misleading measure. Even if you are athletic and well muscled, it still applies, and in that case, you can still be within your healthy range. The range is plenty large.

If you are an adult and you think the BMI is misleading, you are probably in denial about your own shape.

[edit] it seems people like to use examples like professional football players, who litterally add 30% to their body weight in  muscle.  There are two issues here: these people are almost certainly using HGH to attain this amount of mass, and the BMI is still relevant in that muscle weight is approximately as taxing on your heart as fat weight, pound for pound.  Despite the fact that you may not want to lose the muscle weight, you can still be over weight.

IGN is simply incorrect. 

Since someone deleted my thread about the video review of IGN about Wii Fit, I dunno why so I might aswell post the link here:

I just got Wii Fit and it is a good excercise game

Exactly.

I have never understood why Nintendo gamers feel that reviewers need to learn how to review "casual" games, or apply a different standard to them. A very large majority of the target audience for "casual" games are not reading the review anyway and therefore it makes no sense to write reviews directed to them.

8 is a good score for the game. In fact it's a very good score. I cannot imagine why anyone could complain about Wii Fit receiving that score (unless they thought it was too high).

BMI is an awful measure of health that is almost entirely useless. It is of practically no relevance to almost anyone who is healthy and in reasonably good shape. It is worth noting that I can say this whilst completely disregarding the likes of athletes.

BMI is quite simply a superficial measure of health, it unambigiously fails to analysis the complexity of issues that make up ones health. In gaming terms it would be like measuring a games greatness by its back cover without ever checking its content by playing. In short, it's quite stupid.

Then will you please explain how Wario Ware has a review average over an 8. It is just a mini game collection.

 Then care to explain why Wii Sports have a score of 7.5 and Wii Play have a score of 5.5 then, even with the free wii remote? Like I said, core reviewers hardly make casual games a score of 8. And the Warioware review just proves it, do you know that Wii Sports have the most nominee and won the most innovative game of 2007 in the last Bafta awards? Most innovative game, gives a score of 7.5 while a niche game like Wario Ware gives a score of 8, LOL.

Now for your post, do you know that Rayman raving Rabbids scored an 8.3 3 points higher than Wii Fit even its only just a minigame compilation cash in made by Ubi? LOL WUT? O_o Anyway, I've played part 2 and it just bore me within days and I never buy the first one since part 2 was just a rehash of the first one with updated graphics. (Which means its just the same game)

Now you see what I mean?
