More HereIt's been nearly five years since Nintendo unleashed Mario Kart Double Dash on the GameCube and, if you can believe it, roughly 16 years since the kart racing series first kicked off on the Super Nintendo. The popular series has, like the traditional Mario platformers, become a staple of all Nintendo's platforms. So, in that regard, the announcement of Mario Kart Wii is hardly surprising. However, the big question mark for fans has been what, if anything, is going to be done to advance the gameplay and how is the game is going to take advantage of the Wii. Nintendo recently had us over to their Bay Area offices to get a look at a work-in-progress version of the game that's looking like it will remain true to the spirit of the beloved series.
