Kart of all Kart games!

The Best Kart game ever!>
When I first bought this I was a little worried, having played the GBA verson; I was afraid of the hard learning curve. As soon as I turn it on I was hooked. I got to relive courses from the past and new inventive corses. My faves include Waluigi Pinball, Delfino Square, Luigi's Mansion. The singles courses are challenging as you move up levels. I'm still trying to get three stars on all tracks.
Another great feature is that you play up to eight people via wi-fi local with one card. I tried it out a party, and we had a blast, although to make it fair, the one with the game in its slot has to choose a slow car, since all the others have shy guys with slow cars.
The online support is another great feature, you can play region or worldswide. They're a limited courses that you can play on. My tip for all, master the Rainbow course, you be raking in lots of wins if you perfect it. It also includes you friend codes, but call them ahead when playing, that way you play at the same time.
The con in online are the cheaters!
My record is 314-320 as I write this review. More than half of my losses are because of cheaters. You can drop out of the races if your opponent is cheating, but you are given a loss, sometimes two. Another, when you are going to win your cup after the fourth race and your opponet loggs off before you finish you aren't credited with the wins. I hope one day Nintendo can address these problems one day.
Anyhow, as side from these minor problems, I highly recommend this game with the highest rating! So much so I plan to buy another copy for my sons.
