Possibly one of the greatest DS games ever produced.
Although, this game does unfortunately have a down side. Nintendo Wi-Fi is densely populated with many Japanese Mario Kart owners. This can get particularly annoying as the majority of the time they seem to be exceptionally good. "Snaking" is also an often thing used on Wi-Fi by racers worldwide, this is were you drift from side-to-side on a straight piece of track using the mini-turbo each time. This provides the user with more speed. The time trials often loose their fun after time. The Staff Ghost-Data is pretty challenging on most race-tracks which also gives time trials boredom.
Mario Kart, however, is one great game for the DS! The Nintendo Wi-Fi Connection feature gives the game endless challenges and amusement. Grand-Prixs keep you racing to achieve "star-ranks" and unlock a range of characters.
If you own a DS i recommend you should buy this as it is a fantastic game produced by Nintendo. I also advise that many Mario Kart racers believe that Yoshi is one of the best performing characters and that the Poltergust 4,000 is a great car. I'm not saying these are perfectly true; it is just what i have heard.
