Mario Kart changes quite a bit but in a very different way than most games change ... Nintendo maintains most of the core gameplay elements that people really enjoy, and then they add gameplay elements on top of that in order to create variety and give each game its own distinct flavour. |
examples? The only one that did things to shake things up was Double Dash. Adding a new item or something really isn't a big deal. Mario Kart games rarely change the core gameplay.
