Mario Kart World's new gameplay showcase puts a lot of focus on the game's Tony Hawk-style rail-grinding mechanic, and in doing so proves it's more than just a slick gimmick.
When I first saw Mario Kart World racers hopping onto rails and pulling off li'l spinny tricks, I figured that was about the size of it. At best, I thought, it was a cute but impractical mechanic that would give you a little speed boost that may or may not compensate for the slight deviation in your path to the finish line, but after watching today's Treehouse livestream, it seems rail-grinding is much more central to the game's meta than I had initially thought.
