New mario karts have consistently had new ideas and gimmicks. The fundamental formula of "battle racing game with karts" is the same but they've added in things like duo-karts or flying karts or bikes and very different race track design to give it a fundamentally "different" element from game to game. You can see a different gimmick in each one.

With F-Zero it's literally just ultra high speed racing with damaging walls that inflict car damage over time until your car explodes. The goal being to race as hard and fast as possible while getting heals each lap and managing your endurance to not blow up.

Street Fighter isn't Nintendo it's Capcom, but they do add a new core mechanic to each game to fundamentally change the game in a way that makes it fresh each time, the current one being Drive Rush.
