Although a local multiplayer mode is available (up to four players via a single cartridge), there's no sign of online play. Considering the origins of the game and the fact that both GRID and V8 Supercars 3 supported it, this is pretty disappointing. Even an option to trade custom tracks online would have been nice. Time restraints, perhaps? That said, Trackmania DS is strong enough – there's plenty to keep you amused, with over 100 tracks and a number of play modes. A very enjoyable 'pick up and play' experience, and one of the best arcade racers to hit the system in quite some time.
