No other kart racer matters now that this game has completed its Grand Prix seasons. Nearly a year of free DLC (which included new maps, characters, karts and various skins/paint jobs/tires) included with the base game on top of the already wonderful Adventure mode PLUS all the tracks from Nitro Kart all redone in a beautiful HD environment with some of the best kart racing physics/item usage in a game like this makes this the best kart racer I've ever played and puts the rest of the genre to shame. Comparing it to Mario Kart which has the obvious catch up mechanics with items, items here can be obtained all over the place so if you're good, you can really shine without getting hit by some bullshit red/blue shell while you're owning.
