In a word...THE BEST...oh wait thats two words....well, you know what i mean!!
Gameplay - Top notch! the courses are varied in both length and complexity with enough short cuts and hidden extras to keep you going long after you beat the game first time round.
Visuals - This is the Wii were talking about so we cant expect too much. That being said they are among the best on the console to date. More importantly, there is no lag...even in online multuplayer.
Online - The crowning achievement in this package. it is simple to set up and simple to use. There is zero lag which lends itself to an exhillerating race.
The Wheel - I was among the sceptics when this was announced. i thought that it would be unresponsive and thoroughly pointless, expecting to relegate it to the loft along with all the other console racing wheels! This one however is perfect. it is as responsive as could be, with even the slightest move of the wheel reflected by your character.
To summise it is without a doubt the bext Mario Kart to date. If i have one gripe its that they have rehashed old courses from previous Mario Kart games. Whilst a nostalgic trip down memory lane is fun for a few hours, it soon becomes, 'been there, done that' and you find yourself restricted to the new courses.
