Mario Kart Wii isn't another recycling of the series—it's an excellent entry with several new additions. Motorbikes are a blast to race on, the new trick/boost system is fused well into the traditional gameplay and the new tracks blend in outstandingly with old-school ones. The big expansion here, however, is the infusion of Nintendo Wi-Fi Connection. A Mario Kart universe awaits you, complete with online play, ghost racers and competitive rankings. The overuse of power-ups is blatantly ridiculous and the general design hasn't changed much, but Kart is still a riotous romp.
