DS is by far the peak

>highest skill ceiling
>tight controls
>expansive solo mission mode
>battle mode that can be played alone vs CPU
>first true online Mario Kart

Super Circuit is shit. Imagine having 3D MK for 5 years then this shit releases.

MKDS will forever be the best one. It has the highest skill ceiling, expansive solo mission mode, can play battle mode vs cpu, and it has the best tracks
