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

Execution · Pure Mechanics
A futuristic Call of Duty whose exoskeleton boosts made aerial movement king.

Execution · Pure Mechanics
The first online Mario Kart, infamous for the execution-heavy snaking technique dominating play.
Call of Duty: Advanced Warfare leans Execution (Pure Mechanics); Mario Kart DS leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Advanced Warfare
Exo boost-dodging raises the mechanical ceiling sharply
Mario Kart DS
Snaking demands relentless precise drift inputs
Call of Duty: Advanced Warfare leans a little harder on reads, though the gap is small.
Call of Duty: Advanced Warfare
Predicting human boost paths wins gunfights
Mario Kart DS
Online opponents punish predictable lines
Mario Kart DS leans a little harder on variance, though the gap is small.
Call of Duty: Advanced Warfare
Spawns and supply-drop loot add randomness
Mario Kart DS
Item RNG decides tight finishes
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Advanced Warfare
Movement tech and class builds are learnable
Mario Kart DS
Kart stats, lines, and snaking routes
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.
