head to head
Super Mario Kart asks more than Grand Theft Auto V, and the gap is execution.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Execution · Practiced Mastery
The original kart racer where drift technique fights item luck on Mode 7 tracks.
Grand Theft Auto V leans Execution (Practiced Mastery); Super Mario Kart leans Execution (Practiced Mastery).
Super Mario Kart leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Super Mario Kart
Hop-drifting Mode 7 corners is genuinely technical
Super Mario Kart leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Super Mario Kart
Two-player battles reward predicting the rival
Super Mario Kart leans clearly harder on variance.
Grand Theft Auto V
Some mission and lobby randomness.
Super Mario Kart
Item rolls swing close races
Super Mario Kart leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Super Mario Kart
Racing lines and shortcut mastery
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
