head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A gritty WWII Call of Duty that introduced the Zombies mode.
Execution · Practiced Mastery
The original kart racer where drift technique fights item luck on Mode 7 tracks.
Call of Duty: World at War leans Execution (Practiced Mastery); Super Mario Kart leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: World at War
Twitch gunfights in fast multiplayer lobbies
Super Mario Kart
Hop-drifting Mode 7 corners is genuinely technical
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: World at War
Human opponents reward positioning prediction
Super Mario Kart
Two-player battles reward predicting the rival
Super Mario Kart leans a little harder on variance, though the gap is small.
Call of Duty: World at War
Random lobbies, spawns, and zombie waves
Super Mario Kart
Item rolls swing close races
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: World at War
Perk loadouts and map control are 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.
