One of the best games on DS to this date!!
User Rating: 9.2 | Mario Kart DS (DS Bundle) DS
The wi-fi makes a great addition to this. If it wasn't for that, this game would've gotten boring and short. The next you'll know is that there are gonna be loads of pre-owned mario kart DS boxes on shelves in a games store! The graphics is brilliant for the ds as well! Just compare it to the graphics on lets say........Need for speed: most wanted. Graphics are barable on that but then when u play this, You'll think "wow...what was i thinking of when playing this crap?!"
It would have been better if it was like double-dash (gc) and control two characters.
This game is easy to get used to as well. The controls are spot on. On the top screen, you see your character racing. On the bottom screen, you see the circuit you're racing on, another great reason for the ds to have two screens! All in all, a must buy for all ds owners
