Mario Kart Wii does half of what I'm talking about.
Nintendo didn't reinvent the wheel--Ha!--with Mario Kart Wii. Many of the features present in the previous console entry, Double Dash!!, were discarded in favor of a return to the basics. You won't find two riders to a cart (and with it, co-op play) or character-specific items here. Instead, Mario Kart Wii introduces a trio of new ideas: motion controls, motorbikes, and online play.
The Wii Wheel, packaged with the game proper, provides the purest means of playing the game using motion controls--you can drive sans wheel, but over-correcting becomes a bigger obstacle than the other cheating bastards on the road (more on that in minute). The only problem is that using the wheel places a handicap upon you. There's a level of precision inherent in using the Nunchuck/Remote combo and the Classic Controller (my personal recommendation) that the Wii Wheel just can't match. On the harder difficulties, that just may be the difference between first and last.

The Motorbike, the second of the three major additions to the game, differs only slightly from carting: instead of relying on power turns for boosts, the bikes use a wheelie mechanic in order to gain boosts. This gives birth to a new form of the dreaded snaking technique. Stringing together wheelies allows you to essentially maintain a slight boost throughout the entire race. It's a difficult technique to master, but there's always some asshole out there working to perfect it.
And you will run into him. Mario Kart Wii introduces probably the best online mode in any Wii game to date--which isn't saying much, because it's still hampered by the dreaded friend codes and lack of voice chat. Playing with your buddies can be a hassle, but jumping into a race with some random gamers worldwide is painless. Now, talking trash after a particularly close race would be the only addition this mode would need.

For each insipid, stupid-ass turn the game makes, it never veers off-track enough to kill the experience. This is, after all, Mario Kart. While not the revelation it could have been, Mario Kart Wii provides enough great moments (and provides the only safe way to drink and drive) to make it a worthwhile investment for Wii owners.

Mr. Face say this game GOOD.
Mr. Face never wrong!
