So far, this is the best handheld Mario Lart game ever. If you like Mario even in the slightest, you should get this....

Mario Kart DS is alot like Mario Kart 64. Only this time, the characters and karts are 3D. Once certian conditions are reached, you may use any character on any kart. Two new kart racers are introduced in this game: Dry Bones and R.O.B. These are great additions to the Mario Kart games.

The track's design's are very nice. The artwork has that Mario feel to it because of all those familiar objects in the game. Example, there is a desert track made after the desert stage in Super Mario Bros 3 and there is track made after those flying ships in Super Mario Bros 3.
There are even 4 tracks from each of the other Mario Kart games. (Yes, that includes "Mario Kart Double Dash!!")

The music was okay, but a little on the disappointing side...
The music was not awful, just not as good as it used to be.

One customizable, besides your name, is an emblem you get to make yourself. Your emblem will appear on your kart as you race. Also, while playing on WiFi, others will see your emblem next to your name as you pass them in a race. I created my emblem to be "Dr. Eggman" from the "Sonic the Hedgehog" series. What will yours be??
