A new category to add for end of year considerations in gaming

I'm going to throw something out that I mentioned briefly in another post, and maybe this is something a gaming magazine or website already does.  I think a new category should be added to the fold for the end of the year considerations - 2008's Most Important Game or Innovation.

There are a few games that come to mind.  The most obvious, and my personal choice, is Wii Fit for melding innovation, gameplay, and most importantly, exercise.  It was a bold move by Nintendo, one that has shown some amazing returns financially (and physically, for those of us using the sucker) and future potential.  It's not the cure-all to slug-like metabolism or obesity, but damned if it isn't a great step in the right direction.

There are other games deserving of consideration, too.  I'd argue the following games have all introduced some innovation that has potentially changed the gaming world, be it now or sometime in the future.  Please, feel free to debate and discuss below, but this isn't the place for system flames or trolls.  I'm looking for good, honest debate on which game was the most important of the year.  So here is my full list, which will be edited and updated as individuals bring their opinions to the table:

Spore - for its incredible use of background technology in regards to user-created content
LittleBigPlanet - for the sheer possibilities of user-created content and creator options
The World Ends With You - for its innovations in style and presentation
