Did I mention the graphics? As good as they get on the Nintendo DS. Nintendo really out-did themselves with Mario Kart DS. Also, the superior controls do no harm to the game.
What about the multiplayer? As good as ever. Direct multiplayer is amazing; as always. But where the game really shines is in the Nintendo Wi-Fi Connection. This first ever Nintendo game that takes advantage of the feature that the Big N announced in their Spring 04' E3 Press Conference.
After you play it, you realize why it took so long to bring it out. It's nearly flawless. No connection breakups or anything. I was playing a guy in Japan with a slow connection. The game automatically re-adjusted his choppiness so that I could barely see it. You can also import a friend's DS code to see if he is online looking for a match. Although it is slow to load, and very very slow to find a competitor, (let alone four; the game's max) it is still great overall. Once connected and loaded you have a posse of options to choose from, such as Battle Mode and Versus. Each has a great amount of settings that can be fiddled and tampered with making the game's lastability endless.
However, no game is perfect. To every great game, there are some minor flaws. First off, when you play the last course in retro mode, it automatically skips to the credits once you're done. I don't want to see the damn credits. I turn my DS off and back on, and that really starts annoying you. Especially so when you are stuck on it in 150 CC(Mirror Mode; as I am.) Speaking of Retro Mode, what's with the course selection. I don't know who picked them, but they are terrible choices. Both of these are small prices to pay for one of the best games I've ever played. And what about the difficulty? It starts out easy but then surprisingly becomes one of the most challenging games I've ever played, on any system. That's a real plus to the game as that makes this a great gift for young children, and for teenagers alike.
Overall, if you have a Nintendo DS already, this is a must buy. You have to, it's incredible. If you don't have one yet; this might be the game that would make you want to buy the system. Any fans of the Mario franchise or racing games in general will want this game. And if they don't; something is wrong with them.
