An Amazing game, with the best online the DS has, and it's really ahead of it's time.
Concept: It's a racing game, the gameplay is a little bit different from Mario Kart Double Dash!!, where in this game, you ride the kart with one character, where as in Double Dash!! you can use two character's on one kart, anyway, the gameplay is really addictive and fun + with lag-free WiFi, you can have races with any one over the world and you can play with up to 8 people and it never really get's boring.
9/10
Graphics: Very similar to N64 graphics, and this came out in 2005 and it has graphics that are better than most DS games, and it came out in 2005 and it's really good actually, I don't what more I can say about it.
9/10
Story: It's a racing game, so it doesn't really have a story.
--------------------------------------------------------
Good Aspect: Fun gameplay, Wifi matches that are lag-free and addictive.
Bad Aspect: The game doesn't have a lot of characters and it doesn't have a lot of Kart's, every character has a standard kart and a specific kart for the character and it differ's between character's, but since this is on a handheld, I won't take a lot of point's from the game.
--------------------------------------------------------
Overall: If you like racing games, get it, if you like Mario, get it, and honestly, If you like having WiFi matches, buy the game, It's one of the best games on the DS.
and I give this game a 9.0
