A must buy for DS owners.

i keep falling back on this game. Kind of like I keep falling back on Battlefield 2. The game surprisingly works well with the DS's D-pad. The multi-player is an expected greatness from Mario Kart and they hit this one on the ball. It's wondeful. This was Nintendo's first shot at an online game and they did surprisingly well. They have some things to work out in newer online games but that will be done. This is definitely a must-have for anyone who owns a DS.
