9.5 Presentation
Incredibly thorough single and multiplayer experience with tons of options to beef up the variety. The online component works simply and elegantly, but it's just a little too restrictive.
9.0 Graphics
Super fast, super smooth 3D engine drives the action. All the Mario-esque elements are represented here, and even though the characters are low-poly they still look fantastic.
9.0 Sound
The happy, peppy Mario style of music continues on its happy and peppy direction. Some voice samples are more compressed than others. Stereo effects are outstanding and work well on the DS speakers.
10 Gameplay
This is the best of the Mario Kart best. Kart and weapon balance is incredibly tight, new track designs are fantastic, and the game has an extraordinary amount of playtime well after.
10 Lasting Appeal
If there's any game you'll continuously come back to, it's this one. Single cart, multiple cart, and online multiplayer, and single player finally has "bots" for practicing Battle Mode!
OVERALL: 9.5 INCREDIBLE
Solo queda esperar al 25 de este mes
