So, apparently there was some news yesterday regarding Mario Kart Wii, something that put some more faith in seeing more competitors - no more snaking for the Wii version.
Snaking, if you're not familiar, is a term for power sliding on a straight path in a snake-like motion. The benefit from such an odd maneuver is that, if done properly, every power slide will give you a boost, effectively allowing you to use the power slide boost even on a straight path. The most recent victim of this is Mario Kart DS, where many people have experienced it in one battle or another.
Personally, I'm glad they've reduced it to a point where the boost is determined by the length of the power slide. Maybe perhaps this time there will be more honest races.
