I'm still shocked that Donkey Kong Bananza isn't a system seller for Switch 2. It does a better job at showcasing the system's capabilities than Mario Kart World has.

Outside of Mario the are very few actual platformer system sellers if any, the genre for most part in the modern era has more been one that compliments a platform's library.
