Mario Kart ds is an exceptional game. There's no two ways about it. The format remains the same, but with each incarnation the game improves slighly, and this ds version is no different. All your favourite characters are here, with some extras thrown in. At the start of the game there are 6 characters, and 24 tracks to choose from. In its full unlocked state, the game offers 12 characters and 32 tracks. Not including the mirror mode. Which effectively doubles the amount of tracks. There is also the option to choose different karts for your character, introducing a slight tactical element to the game, but in reality, seasoned players will more than likely see this as little more than a gimmick. All three cc classes are here too, 50, 100 and 150. As-well as the time trial. Retro fans will be satisfied too, with the inclusion of 4 tracks from each of nintendo's retro consoles; the GBA, the SNES, the N64 and the GameCube. The staff ghosts are in there too, so replay value is good. In short, Mario Kart ds is a game that will provide hours and hours of fun. Well worth the money, and definately a keeper. Highly recommended.
