The phrase that sticks out is 'trend setter'.
Trend Setting, in my non-expert opinion, are based off of others' opinions. IF and only IF Wii Fit is popular, will it be more popular, and a trend setter.
I would say that, in order to determine the trend setting, Wii Fit needs to be out for about 3 months before any "Trends" are determined.
DS is a good trend measurement. It got more popular as time went on. Word of mouth, games played, wanted, etc. If a lot of 'normal people', the ones who don't hound forums, websites, or any other media info, don't know of a product, it takes a short while to realize it's even there.
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
