Mario Kart Wii is still a great release. It's very hard to fault the actual mechanics on a gameplay-level, since it all works. As it should – it hasn't had a massive formula or physics change since the N64 version. You'll still have a grand old time mercilessly bumping Toad off the edge of a tight turn in the Mario Galaxy-inspired, new-version of Rainbow Road. The multiplayer battles provide the same thrills on five new maps.
The online play works well and the Mario Kart channel is a good way of orchestrating global events and stat-tracking. For what it lacks in visual punch, the game immediately makes up with a smooth framerate, great draw distance and endearing animations. Mario Kart Wii is eminently playable, excludes no one and incrementally improves many aspects of the series. While Mario Kart Wii is an enjoyable sequel IGN can't help but be a little disappointed that the same level of effort Nintendo put into Mario Galaxy and Smash Bros. isn't mirrored here.
